摘要
主要研究雷达低仰角跟踪中阵列信号处理技术的应用。介绍阵列信号处理技术发展的现状和趋势 ,并简要推演和分析由于多路径效应而造成探测误差的数学模型及其产生的原因。在此基础上 ,详细研究了两种阵列信号处理技术 :相关高度技术 (CHA)和最大似然估计 (ML )技术 ,并做了大量的计算机仿真。仿真结果表明ML技术比 CHA技术有着更好的性能。最后给出了具体的实施方案。
This paper mainly studies the application of array signal process technique(ASPT)in radar low angle tracking.It begins with description of the state of art and trend of ASPT,deduces the mathematical model which has detecting errors because of multipath effect and analyzes the reasons.On the basis of the model,its studies two kinds of ASPT:CHA and ML.The simulation results indicate that ML has better performance that CHA.Finally an engineering plan is proposed.
