Wideband Phased Subarray Jammer Nulling Technique

High-resolution radar imaging systems are vulnerable to external interferences. When jammer power is large, it has a great impact on detectability and identifiability of the target. A jammer nulling method is presented after stretch processing and narrowband filtering which uses LMF signal in this paper. Moreover, The algorithm is simple in computation and easy in practical engineering. At last the computer simulation demonstrates the effectiveness of the method
