Modulus spatially variant apodization algorithm for radar images

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