一种适用于改善跟踪雷达低角性能的研究方法

A Method Used for Improving the Low-Angle Performance of Tracking Radar

为使舰载跟踪雷达能精确地跟踪超低空掠海飞行导弹，在考虑雷达发射频率、天线架高、目标高度、目标速度、航路捷径、海面粗糙度、反射系数、海面扩散因子、地球曲率等诸因素影响的同时，我们采用宽带捷变频与重滤波相结合的方法来改善低角跟踪性能。仿真研究结果表明该方法是行之有效的。

In order to track accurately a very low flying missile over sea,considering the whole influenee of radar RF、 antenna mount height,target height,target velocity, crossroad, rough factor reflection coefficient and divergence factor on the surfaee of the sea、the earth curvature、and so on,we ad opt the frequency agility over a wide bandwith and heavy smothing together for improving the low-angle tracking performance。 Artifial testing results show:this mothod is efficient.
