Abstract

THe binary phase coded waveform (BPCW) is widely used in tracking radars, while the sidelobe suppression filter (SSF) designing methods for BPCW are always limited to short codes such as the Barker code. A new kind of SSF based on time domain synthesis and genetic algorithm (GA) is presented. The filter can be used for various lengthened codes, including the m-sequence etc. Some simulation results of time domain synthesized SSF for the Barker codes and m-sequence codes are given, together with comments on the performance comparison of the new filter with some known filters
