摘　　要：基于相控阵雷达的天线波束形成原理和单脉冲体制测角原理,分析了波瓣分裂对雷达角敏函数曲线的影响以及多路径效应对S波段舰载有源相控阵雷达低空跟踪性能的影响,比较了改善跟踪低仰角目标性能的3种方法如偏轴跟踪和复角技术的现实性和可行性。This paper base upon the phased array radar theory of radar wavebeam and theory of single pulse, analysis on the effection of angle-sensitivity function by wavebeam splitting , and low angle treking quality of S band phased array radar by multipath effect. We compare the reality and possibility about several kinds of approaching trcking quality such as bias axis tracking and complex angle technique on low-elevation angle object.
