Paper Abstract

In this paper, a new method to suppress both barrage jamming and deceptive jamming is proposed based on spaceborne azimuth multichannel synthetic aperture radar (AMSAR). The relationship between signals received over arbitrary channel and reference channel is obtained by analyzing the signal models of the jammed AMSAR. Based on this relationship, a system of equations, whose solution contains SAR echo and all jamming signals, is established. In order to obtain high-precision solutions, the system noise has to be removed and accurate direction of arrival (DOA) estimation of jammers is required. For this purposes, a singular value decomposition (SVD) based method for noise reduction and a least square method for the two-dimensional locations of jammers are put forward. By solving the equations, SAR echoes can be recovered. Finally, several simulation experiments are provided to illustrate the effectiveness of the proposed method.
