摘　　要：机载雷达在飞机飞行的过程中跟踪前方的目标物,由于飞机与目标物的相对位置在不断的改变,因此需要改变雷达天线的波束指向,让雷达波束继续对准目标,所以在飞机飞行过程中需要不断的调整天线波束指向,从而达到跟踪目标物的目的。论文从飞机的匀速直线飞行、偏航、俯仰以及偏航与俯仰同时出现的这4种情况进行理论分析,使雷达天线随飞机运动不断调整天线扫描角度,使雷达天线波束指向目标物,实现雷达天线运动补偿。并用MATLAB软件对雷达天线补偿算法进行仿真。During the flight,the airborne radar is continuously tracking targets ahead. Because the relative position between the plane and the target is constantly changing,the radar antenna beam direction must be adjusted accordingly for the purpose of tracking the target. Analyzed theoretically in this paper are the four kinds of flight circumstances including the uniform straight line,the yaw,the pitch and the yaw and pitch. The radar antenna scanning angle will be adjusted along with the movement of aircraft,which make the antenna beam aim at the target all the time and implement the movement compensation. The radar antenna compensation algorithm is simulated with MATLAB software.
