During the course of developing digital beam forming (DBF) processor of digital array radar, the performance of DBF processor need to be tested with different targets and interferers. It is very difficult to test the performance and function of DBF processor in perfect true environment. So it is necessary to develop a radar simulator to generate simulated base-band echo signals from all patches of DBF receive array. A large number of array patches and complicated, changing targets set a higher demand on the...
