Electromagnetic Environment and Target Simulator for Radar Test

Abstract

This paper describes the design of a general purpose electromagnetic environment and target simulator which is used to test radar and its components. The simulator was a hardware system controlled by computer software which generated echoes of targets, clutter and jamming for radar electromagnetic environment scenario simulation. It responded to the subject radar’s antenna scan by producing composite echoes in real time. Computer programs were used to management the simulation process and allowed various combinations of electromagnetic environment. Parallel signal generator was exploited to increase the execution speed and achieve real-time performance. Since the simulator could produce video frequency and intermediate frequency echo separately it was 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 distinguished the simulator from other pulse-by-pulse simulators that had been previously reported. DOI: http://dx.doi.org/10.11591/telkomnika.v11i7.2816
