An asymptotic method of analysis is studied for the radiation field when the lowest-order whispering gallery (WG) modes propagating from the concave side of the concave-to-convex boundary with a variable radius of curvature are radiated into the free-space on the convex side. The modal ray congruences of the WG mode are radiated into the free space after being converted to geometrical rays. Both the caustics and the shadow boundaries are created in the space. As the expression of the radiated field near the caustic, the modal rays incident into the concave part are used for deriving the physical optics integral. By applying the high-frequency asymptotic analysis in the case of two saddle points closely spaced to the evaluation of the integral, the uniform asymptotic solution was derived. Also, as the radiating field on the sufficiently shadow side of the caustic, the complex ray solution was derived. On the other hand, as the radiating field in the transition region near the shadow boundary caused by the convex region, an asymptotic solution was derived in the form of an extension of the conventional UTD (Uniform GTD) to the case where the geometrical ray converted from the modal ray is incident to the boundary. The numerical results obtained by various asymptotic expressions are compared with the reference solution and the geometrical optics figure drawn by the modal ray tracing. The effectiveness of the asymptotic solution and the propagation and radiation phenomena of the WG mode were derived.

While the end of the Cold War minimized the threat of open ocean naval combat, new littoral warfare missions and threats such as tactical ballistic missiles have emerged. These threats and missions challenge the traditional military standard computing resources available to the Navy--a challenge that is increasingly difficult to meet in a cost effective manner. Furthermore, in recognition of the high cost of military standards, Secretary of Defense William Perry has directed that commercial standards be utilized wherever possible. As a consequence of this changing environment, the Aegis shipbuilding program has begun efforts to replace current military standard computing equipment with both higher performance commercial equipment and newer system architectures, i.e. distributed computing. As a part of this process, the Aegis program Office has collaborated with the Advanced Research Projects Agency (ARPA) to conduct a joint experiment on the feasibility of inserting a number of ARPA-developed distributed computing technologies into the Aegis combat system, The High Performance Distributed Computing program (HiPer-D) was created from this joint initiative. The overall objective of HiPer-D is to validate distributed computing for Navy shipboard combat system applications. This paper presents the results of the first HiPer-D demonstration of commercial computing technology as applied to the Aegis combat system.

This article introduces the concept of a truly Universal Signal Distribution Network. The emergence of fiberoptic technology as a viable signal transmission medium now gives the N avy the opportunity to use Fiber Optic Cabling and Switching (FOCAS) to implement a universal network. A FOCAS Network can handle all present or future shipboard signal distribution architectures such as point-to-point or data bus. Furthermore, compared to existing cable installations, this network offers lower cost through reduction of the number of cables, weight, and volume, freedom from interference and EMP effects, increased redundancy, and higher operational flexibility. In addition, it will easily satisfy all future expansion or changes in signal distribution by providing at least a ten fold increase in data rate capacity over existing electrical cabling. This last feature alone holds the potential for allowing upgrading and conversion of modern combat systems without need for adding new cabling in the ship. Along with the introduction of the concept of a Universal FOCAS network and its practical benefits and capabilities, this article presents a trade-off between the Radar Data Distribution Network on the FFG and an analogous FOCAS network. Though far from optimized, the resultant FOCAS network shows that the conversion of existing shipboard networks to FOCAS is straightforward and provides a reduction of at least 90% in cable volume and weight and lower cost in cable purchase and installation.

His current assignment is Assistant Manager for New Developments of Missile and Gun Fire Control Systems for the U.S. Navy. He is a member of the Tau Beta Pi and Eta Kappa Nu Honorary Societies.

The MK 92 Fire Control System (FCS) & a new, integrated, highly reliable and light-weight U.S. Navy Fire Control System for missile and gun control. This system, which is in production for the FFG, PCG, PGG and PHM Ship Classes, provides the detection and automation required for modern naval warfare. Search radar data & presented at a very high rate at the operator's console, a highly integrated man-machine interface. Utilization of monopulse and “track-while-scan” techniques result in multiple target tracking capability. The system console(s) offer a self-contained command and control capability and, in addition, standard digital computer channels provide the versatile interface with the ship's command and control, integrating the complete engagement process. Error cancellation techniques are employed to obtain high performance accuracy even under severe environmental conditions. The low manning requirement for both operation and maintenance is a key system attribute for all applications. Comprehensive “at-sea” evaluations, performed by the U.S. Navy, demonstrated successful system operation in all modes of surveillance, multi-target tracking and simultaneous missile and gun engagements. The “at-sea” performance record of the FCS MK 92 was cited by the Chief of Naval Operations to have established new standards for Naval Surface Weapons Systems.

作者： Aoki, Y Iijima, T Member Japan Advanced Institute of Science and Technology Hokuriku Ishikawa Japan 923 Yasubim Aoki:graduated from the University of Kanazawa Faculty of Engineering Department of Electrical Engineering and Information Science in 1992 and received his Master's degree in 1994 from the Japan Advanced Institute of Science and Technology Hokuriku Department of Information Science where he is currently in the doctoral program engaged in research on pattern recognition. Honorary Member Taizo lijima:graduatedwith a B.E. degree from the Tokyo Institute of Technology in 1948 and received his Ph.D. degree later. He joined the Electro-Technical Laboratories in 1948 and since then has been involved in research on electromagnetic theory and pattern recognition theory image processing voice recognition and research and development of OCR. After serving as the head of Iijima Special Research Laboratories he became Professor at the Tokyo Institute of Technology in 1986. He because Professor Emeritus of that institute in 1986. He became Professor at Tokyo Engineering University and Professor Emeritus there in 1991. In 1991 he became Professor at the Japan Advanced Institute of Science and Technology and was appointed Vice President of the institute in 1992. He served successively as editor examiner secretary of general affairs inspector counsel committee-head of pattern recognition and specialized studies head of Tokyo chapter and vice president of this institute. In 1991 he became Honorary Member. He received the Paper Award from the Institute four times and the Literary Works Award once. He received the Achievement Award and the Distinguished Service Award in 1976 and 1989 respectively. He received the Purple Ribbon Medal from the Emperor in 1989.

Theoretical studies on Iijima's ''Theory of Pattern Recognition,'' which is known as a method of multiple similarity, have shown clearly that there are situations when it is difficult to determine the viewpoint and visual field, important parameters to introduce topological aspects into the pattern space, observing a figure itself. To cope with this problem, this paper proposes transforming the observed image from a figure f(r) to a second-order differential image rho(r), called ''figure source.'' The aim is to reconstruct the theory in such a way as to enable the application of similarity evaluation methods as in the conventional case, without compromising the current theory, and all the necessary proofs are given. In this paper, the figure source equation as well as rules representing its properties are developed, and several related physical quantities are redefined.

NAVAL ENGINEERS JOURNAL 1979年第5期91卷 65-73页

作者： BOLD, NT BOURETTE, AP Dr. Norbert T. Bold graduated from Marquette University and later received his M.S. and Ph.D. degrees in Electrical Engineering from Northwestern University. He served three years as a Naval Engineering Officer aboard an Aircraft Carrier and a Minesweeper and has nineteen years technical experience in shipboard navigation underwater target and SDMS projects for the Navy. He is currently a Program Manager in the Autonetics Marine Systems Division Rockwell International where his primary assignment is the development of advanced concepts and applications of SDMS to Navy programs. He has published several technical papers. was elected to four Scholastic Honorary Societies and was the recipient of a NROTC Scholarship. Mr. A.P. Bourette Manager Systems Applications Autonetics Marine Systems Division. received his B.S. degree in Mathematical Physics from Long Beach State University. He began his career with a Computer Analysis Unit. performing tasks related to computer application. programming and interfacing. He has made significant contributions to the Central Computer Complex approach adopted for the SSN-688 Combat System and has performed inertial systems engineering efforts on the MK2 SINS for the POSEIDON Program. He spent some time in the Washington D.C. area providing technical expertise to various Navy organizations. Upon his return he soon was selected to manage the Systems Applications organization at Rockwell International. This organization is primarily responsible for the Shipboard Application of SDMS. He has directed several application studies showing the significant advantages associated with multiplexing. Recently. he provided the technical direction for the FY80 SSN SDMS Preliminary Design Phase.

Rockwell International is currently under Navy contract to fabricate the engineering Development Model (EDM) of the Shipboard Data Multiplex System (SDMS) for general data transfer aboard surface ships and submarines. The application of SDMS significantly reduces hardware such as cables, switchboards, and Signal Data Converters (SDC), and it provides the capability to add many desired features which are currently not practicable. In applying SDMS to a specific ship, a massive amount of signal data must be considered. The Application Design Automation program (ADAP) is a set of computer programs that have been developed to accomplish this task. ADAP com bines signal population data, ships configuration data, and SDMS hardware characteristics to produce an SDMS configuration layout together with documentation necessary to analyze, evaluate, and implement the system. Specific outputs include hardware requirements, system layout, and interface requirements including wire list information. The Timing, Event and Load Simulation (TELS) program simulates SDMS and provides performance data (system capacity, throughput rate, transport delays) for any system configuration. Conventional SDCs can be elimianted from Navy shipboard systems when SDMS is used. SDMS provides the necessary data distribution, signal conversion, and computer interface. In addition, many functions of the conventional switchboards can be performed within SDMS, thus reducing the size or eliminating conventional switchboards. Very small switch-bomb will provide the necessary control of data distribution. With SDMS, an automatic and continuous Noise and Vibration Monitoring (NVM) capability is readily available. The automated NVM function will enhance the safety, operation, and maintenance of the ship. Problems with machinery or excessive self-noise generation will be detected much sooner, and corrective action implemented on a timely basis.
