雷达导引头真实地杂波数据分析

文章对外场试验得到的大量数据进行筛选,选取一部分有代表性的地杂波加噪声数据加以处理和分析,将处理结果分别与瑞利分布、对数正态分布、韦布尔分布及K分布杂波模型对比,分析实际环境中遇到的地杂波及噪声更接近于哪一种成熟的杂波分布模型。解决实际问题时,雷达信号处理器对回波信号采用非相参积累的处理方法,文中给出了数据幅度非相参积累、功率非相参积累和幅度四次方非相参积累性能的比较。

Research on Real Data of Ground Clutter for Radar Seeker

The mass of data are screened by field test results,and some typical segments of ground clutter and noise data are chosen to be processed and analyzed.Compare the results to four mature clutter model,such as Rayleigh,Lognomal,Weibull and K distributing.Then analyze which clutter distributing model the real data approaches most close.For resolving actual problems,non-coherent integration method is adopted by radar signal processing device.This paper introduces three kinds of non-coherent integration manners of amplitude,power and amplitude quadruplicate and gives their performance comparison.
