Clutter cancellation algorithm based on sparse auxiliary arrays

Adaptive sidelobe cancellation is one of the most effective ways to restrain active jamming, which uses the relationship among jamming signals to form beam pattern nulls in the directions of jamming by assisted receive channels. Thus the sidelobe active disturbance can be reduced significantly. This paper introduced the basic theories of ASLC and the basic requirements of auxiliary antenna´s position firstly. And then this paper is primarily targeted to put forward a reasonable layout of the sparse auxiliary array to counteract the interferences well. And the research is unfolded from two aspects: array resolution and spatial fuzzy. Finally the computer simulation results demonstrated the correctness and validity of the related conclusions.
