多基地雷达现有的抗干扰方法大多基于数据融合处理，没有充分挖掘其抗干扰能力。在多基地雷达中，由于不同散射方向上目标雷达截面的独立性，相距较远的接收机接收到的真实目标回波会相互独立。但是，由于发送到不同方向的干扰信号相同，同一接收机接收到的欺骗干扰会高度相关。因此，在多基地雷达中，真实目标与虚假目标的空间散射特性是不同的。利用这一现象，本文提出了一种基于内曼-皮尔逊引理的基于信号融合的假目标识别方法。该方法通过对不同接收机中任意两个目标的复杂包络进行相关性检验来识别假目标。该方法可以区分任意调制欺骗信号产生的假目标。导出了假目标拒绝概率的封闭表达式。理论分析和仿真验证了该方法的可行性。
The anti-jamming methods available in multistatic radar are mostly based on data fusion processing and therefore do not fully explore its anti-jamming ability. In the view of multistatic radar, the echoes of real targets received by the widely separated receivers would be independent from each other due to the independence of target radar cross sections in different scattering directions. However, the deception jamming received by the same receivers would be highly correlated since the jamming signals transmitted to different directions are identical. Therefore, real targets would differ from false targets in the spatial scattering property in multistatic radar. By exploiting this phenomenon, a new signal fusion-based method for discriminating active false targets from desired real targets is proposed in this study based on Neyman–Pearson lemma. In this method, false targets are identified by correlation test between the complex envelopes of arbitrary two targets in different receivers. The new method can discriminate false targets generated by deception signals with arbitrary modulation. The closed-form expression for the rejection probability of false targets is derived. Both theoretical analysis and simulations verify the feasibility of the proposed method.
