Simulation System Design for Radar Low-Elevation Measurement Algorithm

设计了一套功能完备的雷达低仰角测量算法仿真系统,能够产生不同波段、不同体制雷达在各种海情条件下的海杂波,能够模拟各种多径反射环境下雷达回波视频信号,完成对多种低仰角测量算法的仿真计算,分析并比较算法性能,为雷达系统论证设计过程中低仰角测量算法的选择提供依据。

The simulation system is designed for radar low-elevation measurement algorithm.Sea-clutter and multipath propagation are studied,which affect the detectability and tracking ability of radar to low-altitude target seriously,some more realistic models for sea-clutter and mutipath propagation are concluded and the simulations are accomplished with the software.C2 algorithm,Bias compensation algorithm,dynamic bias compensation algorithm,C2-bias compensation algorithm,bias compensation of C2 dynamic phase estimation and Maximum Likelihood estimation algorithm are adopted to estimate the elevation of the low-altitude target.The simulation results of some scenarios show that these methods are effective and feasible for tracking and measuring elevation in low-altitude.
