Module spatially variant apodization algorithm for enhancing radar images

In this paper, a non-linear adaptive sidelobe control algorithm is discussed and a module spatial variant apodization (MSVA) algorithm is proposed. This algorithm could provide a method different from spatial variant apodization (SVA) mainlobe differentiation, which uses module to differentiate mainlobe. Good result is obtained. Experimental study is conducted to this algorithm by simulation and actual radar image. The result validates effectiveness of this algorithm.
