混合编码雷达信号的正交双通道处理

Orthogonal Two-Channel Processing of Hybrid Coding Waveform

研究了一种用于混合编码雷达信号的基于最小均方误差准则下对互相关干扰和自相关旁瓣进行抑制的方法。该方法利用递归得到的目标距离像信息作为下一次计算的先验信息来自适应地抑制互相关干扰和自相关旁瓣,从而得到最小均方意义下的正交双通道。文中分析了双通道处理模型,推导了正交双通道处理的原理,最后进行了仿真实验。理论和仿真结果表明,该方法是正确可行的。

A new method for suppressing both auto-correlation sidelobes and cross-correlation residues of hybrid coding waveform is proposed based on the minimum mean-square error （MMSE） criteria. The iterative target range profile is taken as apriori information to adaptively suppress auto-correlation sidelobes and cross-correlation residues, so the orthogonal two- channels in MSE sense can be obtained. The two-channel processing model is analyzed, then the principle of orthogonal two-channel processing is deduced. Finally, the simulation is performed. Theory and simulation results show that the method is correct and feasible.
