摘要
欺骗式干扰是对合成孔径雷达的干扰方式之一,由于计算量大,因此很难实施。文中对欺骗干扰的算法进行了分析,改进了一般的对合成孔径雷达的欺骗干扰算法,提出了一种高效的快速算法。一般的算法是逐个计算目标点的信号,然后再累加。通过推导,改成先调制相位再计算信号,得到相应的矩阵运算方式。大大减小了计算量,可以实现干扰信号的实时生成,仿真实验证明了该算法的有效性。
Deceive jamming is one of jamming methods to SAR. But it is hard to put into practice for big amount of computation. In this paper, deceive jamming algorithm is analyzed and improved. A highly efficient fast algorithm was put forward. Original algorithm calculates signal of each cheat-target and adds them together. Improved algorithm calculates modulated phase first and then get the deceive signal. The improved algorithm cuts computation amount and can be used in real time jamming signal generation. Simulation shows that the algorithm has good performance.
