摘　　要：四比幅测向是机载雷达告警接收机应用较多的一种测向体制,分析了其基本原理及其局限性。通过改进布阵方式,研究新的测向方法,提出了一种三维空间比幅测向算法,通过仿真和测试,验证了该三维空间比幅测向算法的有效性。The four amplitude comparison direction finding(ACDF) method is used widely in airborne RWR(Radar Warning Receiver) field. The principle and limitation of the method are presented. By improving the layouts, the new DF method is studied, and a new three-dimensional spatial ACDF algorithm is proposed, the validity of this method is verified by simulation and testing.
