Because of the difference in amplitude and phase between channels,the cancellation performance will usually degrade greatly in adaptive sidelobe cancellation(ASLC) system.The compensation can be achieved by means of a FIR equalizer.This paper deal with the relation between the performance of the equalizer as a function of a set of parameters and the cancellation performance,on the foundation of the channel mismatch influencing the performance of ASLC.Finally,it shows that the channel equalizing scheme can be used for improving the cancellation ratio effectively by computer simulation and performance analyses,and the results will guide improvement of the performance of ASLC in project application.
