In this paper, we had advanced the ameliorative method of wavelet ridgeline based direct wavelet transform, in research based on the intra-pulse characteristic analysis method based on wavelet transform theory. It can effective estimate the phase mutations of the phase-coded signals, reduce the date of the initial frequency estimation error because of interruption and boundary effect, obtain accurate intra-pulse modulation parameters, improve anti-noise ability. The method can solve the complex electromagnetic environment, aviation electronic reconnaissance system for phase-coded signal edc, special system radar signal of reconnaissance.
