Abstract. This paper describes the design of a general purpose multifunction simulator which is used to test radar and its components. The simulator is a hardware system controlled by computer software which generates echoes of targets, clutter and jamming for radar electromagnetic environment scenario simulation. It will responds to the subject radar’s antenna scan by producing composite echoes in real time. Computer programs are used to management the simulation process and allow various combinations of electromagnetic environment. Parallel signal generator is exploited to increase the execution speed and achieve real-time performance. Since the simulator can produce video frequency and intermediate frequency echo separately it can be used for the test of most components of radar. The capability to accommodate dynamic scenarios of long duration in real time for detailed tracking studies distinguishes the simulator from other pulse-by-pulse simulators that have been previously reported.
