The performance of air defence missile radar seeker in low-altitude tracking is mainly effected by the ground clutter and multipath interference. The paper deals with the monopulse radar seeker angle tracking performance under the condition of multipath effect on the basis of radar theory on two unresolved sources. A quantitative approach is proposed for separating true target returns from multipath contamination by use of the Brewster angle effect and the doppler difference frequency between target...

The performance of air defence missile radar seeker in low-altitude tracking is mainly effected by the ground clutter and multipath interference. The paper deals with the monopulse radar seeker angle tracking performance under the condition of multipath effect on the basis of radar theory on two unresolved sources. A quantitative approach is proposed for separating true target returns from multipath contamination by use of the Brewster angle effect and the doppler difference frequency between target and its image. Practical example is also given.

雷达导引头低空性能主要受地杂波和多路径效应的影响。本文利用雷达不可分辨双源理论重点分析了单脉冲雷达导引头在有多路径效应存在时的角跟踪性能,并通过实例建立了利用布儒斯特角效应和目标与镜像的多普勒频率差从多路径干扰中分辨真实目标的定量分析方法。

A new method for improving the low-angle tracking performance of normal monopulse radar is proposed in this paper.It needs only once measurement result,and can converge to the real angle of target in certain initial error range.It is similar to the complex-angle method proposed by S.M.Sherman,but it needs not to assume the reflecting coefficient.Its realization is also very simple.

本文提出了一种用于改善常规单脉冲雷达低仰角跟踪性能的新方法。这种方法仅用雷达的一次测量结果就能使仰角估计在一定的初始误差范围内自适应地收敛到目标的真实仰角。它类似于 S.M.Sherman 提出的复角技术,但不需要假设反射系数,并且实现起来非常简单。

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.

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。
