摘要: 本文利用雙譜分析方法,提出用非高斯AR模型對(duì)雷達(dá)目標(biāo)回波信號(hào)進(jìn)行參數(shù)化雙譜估計(jì)。通過對(duì)實(shí)測(cè)飛機(jī)目標(biāo)回波數(shù)據(jù)的分析,合理地選擇目標(biāo)特征構(gòu)成特征矢量,取得了較好的識(shí)別結(jié)果。

Abstract: With bispectrum analysis, an AR model parametric bispectrum estimation is presented for radar target echoes. A detail analysis of actual aircraft echoes and a reasonable selection of target signature are made, with a formation of signature vector for target identification. The experimental results show that the method is feasible and effective. -
