The traditional method used to extract micro-motion is based on the envelope information of
the wideband echo range profile, the estimation accuracy of the traditional method is
unsatisfactory. To deal with this problem, a new method for parameter estimation of micro-
motion feature is proposed, which is implemented by combining envelope information and
phase information of the wideband echo range profile. Firstly, the Keystone transform is
performed to each segment obtained by segmenting the envelope of the echo range profile …
