ENDO Atmospheric-EXO Atmospheric Radar Modeling Model Description. Volume I. Part 1.

This effort is concerned with the development and implementation of a set of digital computer programs that will augment the RADC digital computer radar simulation tion model procured under Contr F30602-72-C-0393 0170 7201. The computer programs shall consist of a sequence of subroutines that correspond to separate functions such as a chaff model, target model, propagation effects and clutter model. The original radar simulation model will be expanded to include a bistatic capability and will include ECM and phase coded pulse compression receiver techniques. In addition, an interactive system has been designed for the simulation. Using an interactive display, an engineer would be able to understand what is happening by being able to observe results at several intermediate points in the problem. A picture is worth a thousand words. For example, an antenna pattern or waveform response to a target is more meaningful than a long tarle of numerical listings. Parts of the simulation were used by RADC for Deep Space Surveillance Radar DSSR waveform analysis, generating antenna patterns and tradeoffs involving phase shifter bit-size for the Advanced Space Defense Program ASDP. The RADC radar simulation model is being used to support Seek Sail, Cobra Judy, Digital Coded Radar and Seek Sentry. Author
