摘　　要：要实现对逆合成孔径雷达的多假目标欺骗干扰,产生一个良好的、含多个假目标信息的信号非常重要。本文提出了一种新的相位调制系数,并由此提出了三种合成多(两)假目标信号的方法,给出了产生多(两)假目标信号的图像合成系统三种方案,进行了详细的理论分析和仿真实验。结果证明了提出的新的相位调制系数和三种合成多(两)假目标信号方法的可行性和有效性。新的相位调制系数较原有的相位调制系数相比可生成含多(两)假目标信息的信号,而原有的相位调制系数只能生成含单假目标信息的信号。To realize multi-false-target deception jamming against Inverse Synthetic Aperture Radar,it is important to produce a good signal that contain muhi-false-target information. In this paper, a new phase modulation coefficient is proposed, accordingly three methods to synthesize multi-false-target signal are proposed. Three schemes that can synthesize the signal of multi-false-target are given. The theory analysis and simulation tests are also done. The results demonstrate that the proposed phase modulation coefficient and the three methods are feasible and effective. By the proposed phase modulation coefficient, the signal that contains multi-false-target information can be produced, the signal that contain a single-false-target information is produced by the former phase modulation coefficient.
