RJARS: RAND's Version of the Jamming Aircraft and Radar Simulation
This Note describes an updated version of RJARS (RAND's version of the Jamming Aircraft and Radar Simulation). The present RJARS is a many-on-many computer simulation in the C language involving aircraft, radars, jamming systems, offensive and defensive missiles, infrared and optical systems, and a command-control-communications system for the defense. It can operate in conjunction with the RAND programs JANUS and CAGIS. RJARS treats sortie operations and evaluates jamming effectiveness and mission attrition at a level of detail that includes reasonable refinements of equipment operation without excessive calculational complexity. This Note describes RJARS and its sequence of operations, shows how to prepare input files and operate RJARS, gives programming details, and provides a glossary of the approximately 1,100 variables used in RJARS.
