E-2C预警机雷达天线方向图反演和仿真

Antenna Pattern Inversion and Simulation of E-2C AEW Radar

针对典型外军雷达系统天线方向图不可获知的问题,从已知的雷达系统参数出发,基于雷达系统设计、雷达信号处理以及天线设计相关理论,通过合理的推算,建立了E-2C预警机雷达天线仿真模型,完成了对其和通道方位、俯仰天线方向图以及方位差通道天线方向图的仿真。仿真结果与已知的天线参数吻合,验证了仿真结果的可信度,可应用于电子对抗试验中对该预警机的仿真模拟。

Aiming at the unknown antenna pattern of the typical foreign radar system, starting from the known parameters of the radar system, based on the theory of the radar system design, radar signal process and antenna design, the simulation model of the E-2C AEW radar antenna is established through reasonable derivation and calculation. And the simulation of the sumazi- muth antenna pattern, sum-elevation antenna pattern tern is completed. The simulation results are agreed and the difference-azimuth antenna pat- with the known antenna parameters, its credibility is verified, and can be applied to the simulation of the E-2C AEW radar in the elec- tronic warfare simulation tests.
