新信号处理技术下低角跟踪误差分析

Low-angle Tracking Error Under Modern Signal Process Technology

多路径效应是近程反导武器系统中的跟踪雷达无法避免的问题。文中概述了多路径效应的数学模型和在多路径效应下传统雷达仰角角误差仿真算法,并分析了新信号处理技术下的雷达仰角角误差提取算法并在传统的数学模型基础上建立了新的数学模型。对两种角误差提取办法在理论上进行对比后,用MATLAB举例仿真了两种角误差提取办法对跟踪雷达低角跟踪仰角误差的影响,最后对仿真结果进行了分析比较,完善了雷达低角跟踪算术模型。

The muhipath effect is an avoidless problem which the tracking radar among CIWS has to face. This paper introduces the mathematic model of the muhipath effect, gives out the typical radar elevation error model, then the modern signal process technology is brought forward and the paper gives out the new radar elevation error model. Finally the paper compares the new way with the typical way by simulating the low-angle tracking elevation error with MATLAB for example, and analyses the difference between them, completes the low-angle tracking error model.
