Abstract
2-D intermittent sampling repeater jamming to SAR can form multi-false targets in range and azimuth,so it can get good deceptiveness jamming effection,but it exists the common defect of intermittent sampling repeater jamming. In this paper a new method of 2-D intermittent sampling repeater jamming to SAR based on convolution modulation is proposed. The jammer receives the SAR signal and intermittent sample the singnal in 2-D ,then convolves it in 2-D with the expected video frequency signal. By choosing the type of convolution modulation signal,it can flexible and controled jamming effection,and it can overcome the defect of intermittent sampling repeater jamming. Theoretical analysis and computer simulation justify the validity and efficiency of this method.关键词
