摘　　要：针对机载SAR雷达干扰重点掩护区计算问题,提出一种新的实现方法。先计算特定航迹上所有满足干扰效能的雷达瞬时成像区域,获得特定航迹下的干扰有效掩护区;然后以特定航迹为基准进行航迹平移,生成一系列新航迹,以同样方法计算每条航迹下的干扰有效掩护区;最后将所有干扰有效掩护区合并,即可得到干扰重点掩护区域。结合仿真实例进行分析,验证了所提出方法的合理性和可行性。Aiming at the key jamming cover area calculating problem for the Airborne SAR when it is along a known flight path for a reconnaissance mission,a new implementation method is put forward.Firstly all the instantaneous SAR imaging regions are cacaluted which satisfy the efficiency jamming in the SAR platform flight path,and combined with these instantaneous SAR imaging regions to be the effective jamming cover area for the SAR platform flight path;then the SAR platform flight path is transported parallel to generate a series of new flight path,the same method is used to calculate the effective jamming cover area for each SAR platform flight path;and then all the effective jamming cover areas are combined to be the key jamming cover area.The proposed method is analyzed by simulation,and the simulation results validate the rationality and feasibility for the proposed method.
