摘　　要：针对传统比幅体制星载告警系统测向精度较低的问题,在不增加系统接收通道数量的前提下,提出了一种基于比幅比相的星载告警测向方法。研究了基于比幅比相联合测向方法的理论,提高了传统比幅测向系统测向精度。仿真分析验证了该测向方法的性能,仿真结果表明该方法可以有效提高传统比幅体制告警系统测向精度。A new spaceborne radar warning director finding method based on amplitude and phase combined comparison is proposed to improve the direction finding precision without additional signal receiving channels.The principle of direction finding method based on amplitude and phase combined comparison is studied.The direction finding precision of common amplitude comparison method is significantly improved.The performance of the method is verified by simulation experiments.The simulation results show that the new direction finding method can improve the direction finding precision of common amplitude comparison method.
