宙斯盾雷达典型信号处理方法仿真分析

宙斯盾雷达使用的典型信号脉内多载频具有抗截获和抗干扰的突出优势，但其信号处理方法还不是非常明确。以脉内四载频信号为例，对其信号特性及处理方式进行了研究，基于检测概率最优原则提出了可能存在的处理方法，给出了处理框架和流程，特别是对存在瞄准式干扰的情况，采用干扰检测算法剔除受干扰子脉冲，通过信号级仿真比较了两种处理方法在不同场景下的检测性能优劣，所得结论为脉内多载频信号的处理应用提供参考。

Simulation analysis of typical signal's processing methods of Aegis radar

As the typical signal of Aegis radar, the intra-pulse multi-carrier frequency signal has awesome advantages of anti-interception and anti-jamming. However, its signal processing method is unclear. Taking the intra-pulse four-carrier frequency signal as an example, its signal characteristics and processing methods are studied. Based on the principle of optimal detection probability, the possible processing methods are proposed, and the processing framework and process are given. Especially for the case of aiming interference, the interference detection algorithm is employed to eliminate the interfered sub pulses. The detection performance of the two processing methods in different scenarios is compared through signal level simulation. The conclusion provides a reference for the processing and application of intra-pulse multi-carrier frequency signal.
