Abstract：Aimed at STLFMCW signal detection in radar reconnaissance ,the paper combines the optimal LFM detec-tion ability of Wigner-Hough Transform and pulse integration technology .Periodic WHT algorithm is proposed and the properties of the proposed algorithm are analyzed .According to the relationship of STLFMCW and LFMCW ,PWHT algo-rithm is used for STLFMCW signal detection .At last ,it is verified by Matlab simulation .The results show detection per-formance of the algorithm is the same as Pseudo Wigner-Ville transform ,WHT and fractional Fourier transform when SNR is -3dB ;detection performance of the algorithm is better than other algorithms when SNR goes down to -9dB .
