Dynamic analysis of waveguide structures containing dielectric and metal strips is presented. The analysis utilizes a finite difference frequency domain procedure to reduce the problem to a symmetric matrix eigenvalue problem. Since the matrix is also sparse, the eigenvalue problem can be solved quickly and efficiently using the conjugate gradient method resulting in considerable savings in computer storage and time. Comparison is made with the analytical solution for the loaded dielectric waveguide case. For the microstrip case, we get both waveguide modes and quasi-TEM modes. The quasi-TEM modes in the limit of zero frequency are checked with the static analysis which also uses finite difference. Some of the quasi-TEM modes are spurious. This article describes their origin and discusses how to eliminate them. Numerical results are presented to illustrate the principles.

This paper sets forth computer systems architecture concepts for the combat system of the 2010–2030 timeframe that satisfy the needs of the next generation of surface combatants. It builds upon the current Aegis computer systems architecture, expanding that architecture while preserving, and adhering to, the Aegis fundamental principle of thorough systems engineering, dedicated to maintaining a well integrated, highly reliable, and easily operable combat system. The implementation of these proposed computer systems concepts in a coherent architecture would support the future battle force capable combat system and allow the expansion necessary to accommodate evolutionary changes in both the threat environment and the technology then available to effectively counter that threat. Changes to the current Aegis computer architecture must be carefully and effectively managed such that the fleet will retain its combat readiness capability at all times. This paper describes a possible transition approach for evolving the current Aegis computer architecture to a general architecture for the future. The proposed computer systems architecture concepts encompass the use of combinations of physically distributed, microprocessor-based computers, collocated with the equipment they support or embedded within the equipment itself. They draw heavily on widely used and available industry standards, including instruction set architectures (ISAs), backplane busses, microprocessors, computer programming languages and development environments, and local area networks (LANs). In this proposal, LANs, based on fiber optics, will provide the interconnection to support system expandability, redundancy, and higher data throughput rates. A system of cross connected LANs will support a high level of combat system integration, spanning the major warfare areas, and will facilitate the coordination and development of a coherent multi-warfare tactical picture supporting the future combatant command st

Wise investment of Department of Defense research and development (R&D) resources is becoming increasingly important. R&D policymakers and managers use a variety of means to guide their decisions. This paper discusses one of them: technology gaming. Technology gaming is a complement to traditional methods of technology forecasting, with technology gaming providing insights about constraints imposed upon advanced systems and technologies by operational environments and about their interactions with one another. The potential and practice of technology gaming are described, drawing upon experiences acquired from several technology gaming endeavors in 1988, including the Technology Initiatives 88 Game (TIG-88) performed at the Naval War College under the joint-sponsorship of the Office of research, Development, and Acquisition in OpNav (OP-098) and the Naval War College.

JCS Pub 1 defines interoperability as “The ability of systems, units or forces to provide services to and accept services from other systems, units or forces and to use the services so exchanged to enable them to operate effectively together.” With JCS Pub 1 as a foundation, interoperability of systems, units or forces can be factored into a set of components that can quantify interoperability. These components are: media, languages, standards, requirements, environment, procedures, and human factors. The concept described in this paper uses these components as an analysis tool to enable specific detailed analyses of the interoperability of BFC3 systems, units, or forces for the purpose of uncovering and resolving interoperability issues and problems in the U.S. Navy, Joint, and Allied arenas. Also, as a management tool, the components can help determine potential interoperability characteristics of future U.S. Navy BFC3 systems for compliance with battle force systems architectures. The approach selected for the quantification of interoperability was the development of a set of measures of performance (MOPs) and measures of effectiveness (MOEs). The MOPs/MOEs were integrated with a candidate set of components, which were used to partition the totality of interoperability into measurable entities. The methodology described employs basic truth table theory in conjunction with logic equations to evaluate the interoperability components in terms of MOPs that were aggregated to MOEs. It is believed that this concept, although elementary and based on fundamental principles, represents an operationally significant approach rather than a theoretical approach to the quantification of interoperability. The vehicle used as a means to measure the MOPs and MOEs was the research Evaluation and systems Analysis (RESA) computer modeling and simulation capability at the Naval Ocean systems Center (NOSC), San Diego, Calif. Data for the measurements were collected during a Tactical I

Due to demographical factors, there will be a 25% decline in the national labor pool of eligible 17 to 21 year old men by 1992. As the Navy faces fierce competition with other services and private industry for the dwindling personnel resources of the nation, efforts must be made to consider automating certain tasks, especially those that are hazardous, boring, and labor intensive onboard ships at sea. The Surface Ship Continuing Concept Formulation (CONFORM) Program (SEA-5014) sponsored the Naval Surface Weapons Center's Robotics laboratory to identify potential applications of robotic and artificial intelligence systems to operation and mission activities for shipboard use. The results of the investigation concerning applications of robotics to automate the aforementioned tasks are presented. Changes in current manning levels for selected tasks and ship classes, i.e., CVs, CVNs, LPDs, LPNs, and auxiliaries are examined. Future ship designs incorporating robotics, such as the advance based repair (ABR) ship are discussed. Twenty-four applications were cited in the study which include a remote controlled vehicle for flight deck operations, limited tasks in biological, chemical, and radiation environments, computer aided command decision aids, ordnance handling, undersea search, recovery, and salvage, and ventilation duct cleaning. Four of the applications and their subsequent hardware fruition will be discussed.

A METHODOLOGY FOR SETTING COMBAT system REQUIREMENTS

引用

NAVAL ENGINEERS JOURNAL 1985年第4期97卷 274-278页

作者： MENSH, DR The Author received his B.S. and M.S. degrees in applied physics from Loyola College in Baltimore Md. and the American University in Washington D.C. He also has completed his course work towards his Ph.D. degree in computer science specializing in the fields of system analysis and computer simulation. He has been employed at the Naval Surface Weapons Center White Oak Laboratory Silver Spring Md. for the past eighteen years in the areas of weapon system analysis and the development of weapon system simulations. Since 1978 he has been involved in the development of simulation tools that can be applied to the solution of shipboard combat system architecture and engineering problems. Currently at the White Oak Laboratory he is responsible for the application of and further development of the single ship combat system simulation.

This paper describes a methodology for setting combat system requirements for all ship classes. The requirements are determined from a battle group perspective. The methodology uses ship damage as a measure of effectiveness for setting combat system requirements. The ship damage data used was derived from the Navy tactical game (NAVTAG). The methodology that determines ship class combat system requirements consists of a set of logical steps that are iterative by design. It provides insight and valid estimates of numerical measures of defined force requirements at several levels. This process is not trivial; the expected level of effort could be significant. The method consists of five basic stages considered necessary to achieve valid results. These stages are (1) determination of force level requirements, (2) determination of force level capability, (3) analysis of force level capability, (4) determination of class requirements by battle overviews, and (5) determination of class requirements — overall. The methodology was used by the combat system master plan (CSMP) manager for determining top level combat system requirements for individual platforms in a battle group. In addition, once levels of combat system performance have been defined, this methodology generates a quantitative data base that becomes a useful tool in ship combat suite selection. Once alternate combat system suites have been defined, these suites can be analyzed in terms of combat system performance capability versus cost.

SHIP COMBAT system simulation (SCSS)

引用

NAVAL ENGINEERS JOURNAL 1984年第3期96卷 142-148页

作者： MENSH, DR The Authorreceived his B.S. and M.S. degrees in applied physics from Loyola College in Baltimore Md. and the American University in Washington D.C. He also has completed his course work towards his Ph.D. degree in computer science specializing in the fields of system analysis and computer simulation. He has been employed at the Naval Surface Weapons Center White Oak Laboratory Silver Spring Md. for the past seventeen years in the areas of weapon system analysis and the development of weapon system simulations. Since 1978 he has been involved in the development of simulation tools that can be applied to the solution of shipboard combat system architecture and engineering problems. Currently at the White Oak Laboratory he is responsible for the application of and further development of the Single Ship Combat System Simulation.

This paper will describe a combat system integration and analysis tool called the Ship Combat system simulation (SCSS). The SCSS was designed as an analysis tool to study sensor command and control and weapon system integration for shipboard combat systems. The simulation represents the combat system components as nodes in a network. Data flows between the nodes through the links. SCSS is a structured program simulation written in Simscript II.5. The structured program feature allows for ease of combat system reconfiguration into different types of architectures. Consequently, SSCS can be used to study and analyze different combat system architectures. Currently the model has an antiairwarfare (AAW) capability and a partial antisurface warfare (ASUW) capability. The model has been used in ship vulnerability and survivability studies, individual combat system component studies, component trade-off analysis; and total system reaction time analysis. Figure 1 presents a sample of a SCSS link-node diagram. Figures 8 and 9 present combat system sequence and timing diagrams. The model boasts a postprocessing capability that includes both statistics and graphics packages. The SCSS has been developed jointly by the Naval Weapons Center, Naval Ocean systems Center, Naval Surface Weapons Center, Naval Ships Weapons systems Engineering Station, and CACI, Inc. SCSS is supported by naval and industrial laboratories throughout the country. The users of the simulation belong to the SCSS User's Group which meets periodically throughout the year. Members of the User's Group develop equipment nodes and exchange ideas. The User's Group maintains SCSS configuration management allowing for Simscript II.5 code written by any one user to be used by all other users.

During periods of radio silence under Emission Control, communication depends on the slow ship-to-ship, manual-visual, 8-10 wpm Morse code signaling shutter searchlight employing the ac 1000-watt incandescent or the ac 1000-watt compact arc mercury-xenon lamp. These sources can be replaced by the dc compact arc xenon lamp to provide longer daylight ranges and highspeed (100 wpm teletype, 150 wpm Morse code, voice, etc.) communication since this source has superior brightness and the facility of considerably more rapid modulation. The excessive weight and size of the ac-dc power convertor and modulating circuitry which had prevented use of the dc xenon lamp have been overcome by developments in solid state electronics such as the rapid, high current, simmer-flash, 100 to one light output xenon lamp pulsing using the reliable, uncomplicated, low-cost silicon controlled rectifier shunt switch which could eliminate the mechanical signaling shutter. laboratory and sea evaluations have proved the feasibility of and provided the long daylight high-speed optical communication ranges that could be attained from operation of the dc 1000-watt and 2200-watt xenon lamps at the focus of 12-inch, 18-inch searchlights and in the Fresnel lens omni-directional beacon which a command ship uses to signal all ships in a task force at once. With these advances, optical communication provides the highspeed capability of radio communication, particularly, also, with the new omnidirectional transceiver.
