Abstract
When the Doppler frequency of target mismatches the fast Fourier transform (FFT) bin frequencies, the high side lobe appears. Discrete wavelet transform (DWT) has been applied to output of weighed FFT (WFFT) to suppress side lobe. And then FFT/WFFT-DWT is proposed to improve processing gain (PG) further. PG formulae for both WFFT and WFFT-DWT are given. Experimental results demonstrate that FFT/WFFT-DWT can attain much higher detectability than FFT/FFT-DWT as well as FFT in unmatched state
