详细分析了雷达采用复角法 (CA)来进行低角度目标跟踪的原理、方法及在实际应用中存在的问题。提出了一种应用于天线高度 /雷达波长比较大雷达的改进复角法 ,并给出详细的计算步骤。通过对某岸基雷达分别采用原方法和改进方法进行的一般性仿真对比研究 ,得出了非常有益的结论

Complex Angle technique for low-angle target tracking with monopulse radars in the presence of multipath effect is analyzed in this paper, including the theory, technique and some problems in application. A technique of modified CA is developped, which has a new algorithm for the distance computation in the complex angle plane. The simulations are based on a coast-sited radar with two CA methods applied respectively, and useful conclusions are obtained.
