本文利用双谱分析方法,提出用非高斯AR模型对雷达目标回波信号进行参数化双谱估计。通过对实测飞机目标回波数据的分析,合理地选择目标特征构成特征矢量,取得了较好的识别结果。
In this paper, bispectrum analysis method is used to estimate the parametric bispectrum of radar target echo signal with non-Gaussian AR model. Through the analysis of the target echo data of the measured aircraft, the target features are reasonably selected to form the eigenvectors, and the better recognition results are obtained.
