Application of computer graphics to tactical displays should not default to simplistic expectations or to clever uses of color. Under the sponsorship of the Aegis shipbuilding project we have defined a method of applying advanced graphics techniques to command displays that asks “What is the display to do?” rather than “What color shall be make it?” The target display is the Aegis display system tactical plot, or track picture. This display has evolved to include graphic elements representing the environment, combat system capabilities, and battle plans. If these elements are all needed in the same display the resulting picture has the potential for great complexity. This paper provides a method for designing uncluttered displays that contain the needed amounts of data. The method develops displays from primary system requirements and includes a computer program (a rule-based system) that assigns hardware attributes (including gray scale, color, and area fill) to components of the picture (display elements). The resultant display is data intensive but not overwhelmingly complex.

BIONDI, RJPRIDE, RWMURRAY, HDWHEELER, PKRoy J. Biondi:received his B.S.E.E. degree from the University of Illinois and has since taken additional graduate studies at the George Washington University. Currently
he is head of the Communication Systems Application Branch code PDE 110–14 within the NAVELEXSYSCOM. Prior to his present appointment he served in the Combat Systems Division Naval Sea Systems Command and served as radar branch head in the former Naval Ship Engineering Center (NAVSEC). He was responsible for development and production of shipboard radars such as the AN/SPS-48 AN/SPS-49 AN/SPS-52 and AN/SPS-55. His primary Navy radar and combat system experience was attained during his earlier career in the Navy's Bureau of Ships where he was the AN/SPS-48 radar project engineer. In addition to ASNE which he joined in 1977 he is a member of IEEE and ASE and has had several technical papers published on radar radar antennas radar processing and transmission lines. Mr. Biondi has a total of 25 years naval experience in radar combat systems and communications. Richard W. Pride:received his B.S.E.E. from the University of Maine in 1959. Currently
he is head of the Combatant Ship Section code PDE 110–143 in the Communications Systems Application Branch within the NAVELEXSYSCOM. Prior to joining the Naval Electronic Systems Command in 1974 he was the head of the Communication Antenna Design Section of the former Naval Ship Engineering Center. Harold D. Murray:received his B.S.E.E. from Vanderbilt University. Currently
he is an EXCOMM program manager code PDE 110–1433 in the Combatant Ship Section of NAVELEXSYSCOM. As an EXCOMM program manager Mr. Murray is responsible for the external communications system design for the CG-47 (Aegis) class cruisers. Mr. Murray's previous government service includes 14 years at the Naval Research Laboratory (NRL) and 5 years at Naval Air Systems Command. Major areas of responsibility included shipboard RF distribution systems and aircraft intercommunication systems and control. Paul K. Wheeler:is pre

External communications is a critical element in the U.S. Navy design and utilization of a ship's combat system. The communications antenna system is a key factor in attainment of reliable circuit performance and reduction of electromagnetic interference (EMI). To maintain pace with improved ship manufacturing techniques and construction materials, along with design efforts to reduce topside generated EMI/RFI effects, an improved antenna design must also evolve. With the ever increasing complexity in the integration of the topside environment, the RF aspects of the antenna designs must be augmented by detailed analysis of the operating environment and the mechanical design if the goals of reliability and quality performance are to be achieved. The Naval Electronic Systems Command has developed a new “Broadband HF Communications Antenna.” This paper traces the design evolution and describes the processes in determining current design deficiencies, the design objectives to correct these deficiencies and the results obtained.

PAIGE, KKCONVERSE, RAUSNLCdr. Kathleen K. Paige
USN:graduated with a BA from the University of New Hampshire in 1970. She received her commission from Officer Candidate School in April 1971 and performed her first tour of duty with VFP-63 NAS Miramar. LCdr. Paige then received her MS from the Naval Post Graduate School in June 1976 and returned to San Diego to serve as Head Support Software Division at the Fleet Combat Direction System Support Activity. In May 1981 she reported to NA VSEA (PMS-408) where she served initially as Chairman of the NAVMAT Software Engineering Environment Working Group. She has been assigned as Deputy AN/UYK-43 Acquisition Manager since October 1981. LCdr. Paige was designated a fully qualified Engineering Duty Officer in December 1983. Robert A. Converse:is presently the Acquisition Manager for the Ada Language System/Navy (ALS/N) for the Naval Sea Systems Command Tactical Embedded Computer Resources Project. As such
he is responsible for the definition and development of the ALS/N to be provided as a Navy standard computer programming system for Navy mission critical applications. Mr. Converse received a Bachelor of Science degree in Physics from Wheaton College Wheaton II. He spent fourteen years with the Naval Underwater Systems Center Newport Rhode Island during which time he designed and developed the Fortran compiler for the Navy Standard AN/UYK-7 computer. Also during that period he received a Master of Science degree in Computer Science from the University of Rhode Island. His thesis for that degree was entitled “Optimization Techniques for the NUSC Fortran Cross-Compiler”. Mr. Converse started his involvement with the Ada program in 1975 with the initial “Strawman” requirements review. Subsequently he was named as the Navy Ada Distinguished Reviewer and was intimately involved in the selection and refinement of the Ada language as it evolved to become ANSI/MIL-STD-1815A.

The U.S. Navy introduced the use of digital computers in mission critical applications over a quarter of a century ago. Today, virtually every system in the current and planned Navy inventory makes extensive use of computer technology. Computers embedded in mission critical Navy systems are integral to our strategic and tactical defense capabilities. Thus, the military power of the U.S. Navy is inextricably tied to the use of programmable digital computers. The computer program is the essential element that embodies the system “intelligence”. In addition, it provides the flexibility to respond to changing threats and requirements. However, this very flexibility and capability poses a host of difficulties hindering full realization of the advantages. This paper describes the lessons learned about computer programdevelopment over the past twenty five years and discusses a software engineering process that addresses these lessons. It then describes how Ada and its related Ada programming Support and Run-Time environments foster this software engineering process to improve computer program productivity and achieve greater system reliability and adaptibility. Finally, the paper discusses how the use of Ada and its environments can enhance the interoperability and transferability of computer programs among Navy projects and significantly reduce overall life cycle costs for Navy mission critical computer programs.
