摘要

提出了一种新的雷达目标识别方法。雷达目标的飞机编号由中频雷达回波识别。对于接收到的中频回波信号，通过FFT和频谱移位得到信号的复包络，并计算其自相关矩阵。特征向量是自相关矩阵的特征值。利用子空间划分的方法，构建了精确的参考模板。

Multiple target recognition by eigenvalue estimation

A new method of radar target recognition is presented. Aircraft number for a radar target is recognized by IF radar echoes. For a received IF echo signal, the complex envelope of the signal is obtained by the FFT and spectrum shift, and its autocorrelation matrix is computed. The feature vector is the eigenvalue of the autocorrelation matrix. Also, using a method based on subspace division, precise reference templates are built.
