Abstract
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.
