摘　　要：微波着舰引导系统(舰载MLS)采用相控阵天线和时间基准波束扫描原理,实现对舰载机着舰的精确引导。舰体运动会引发天线各振子相对位置的改变,导致系统引导误差。通过建立舰载MLS相控阵天线方向图及振动误差模型,针对相控阵天线3个轴向随机运动模式对引导性能的影响进行仿真分析,提出了一种舰体运动造成的舰载MLS引导误差的抑制方案。仿真结果表明,该算法可以稳定地跟踪舰体的随机运动,对舰载MLS相控阵天线进行三维运动补偿,有效改善接收端的信号质量,从而一定程度上提高舰载MLS的引导性能。In order to provide precise guidance for the landing of carrier-based aircrafts,the phased array antenna and the principle of time reference beam scanning are used in the carrier-borne Microwave Landing System（ MLS）. Ship motion may change the relative position of antenna elements,which will cause the guidance error. In this paper,the models of phased array antenna pattern and antenna vibration error are established,a simulation analysis is made to the effect of phased array antenna＇s random vibration in three axial directons on the guiding performance of carrier-borne MLS,and a scheme is proposed for suppressing the guidance error of the MLS caused by ship motion. The simulation results show that,the algorithm can stably track the random motion of the ship body,make motion compensation to the phased array antennas of carrier-borne MLS in three dimensions,greatly improve the quality of the received signal,and improve the guidance performance of MLS to a certain extent.
