Abstract This paper studies a method using wavelet transform to estimate the signal’s spec-trum.The method is applied to the practical MMW radar targets echo signals,and on the condition of the same sampling frequency and sampling data length,it can achieve one dimen-sional range profile with profile’s resolution superior to FFT’s,so the one dimensional range profile of targets can be analyzed with high resolution,there is certain significance in the prac-tice.
