Abstract:

To meet the needs of testing the majority of radar system,scene system must generate all kinds of high quality radar signal.A universal scene system for generating radar signal is proposed.There is a Broadband signal modulation system that has function of calibration,this system consist of AWG 7082C Arbitrary Waveform Generators,E8267D Vector signal generator and N9030A Signal Analyzer.It can compile a series of common radar signal by Pulse Building software.Test results show that the system can create all kinds of radar signal to test most of radar system excellently,especially the calibrated system can restrain image frequency perfectly.

Key words: radar signal simulation;scenario generation;pulse compression;quadrature modulation;image rejection
