Title:
PULSE DOPPLER ULTRAHIGH SPECTRUM RESOLUTION IMAGING PROCESSING METHOD AND PROCESSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/202068
Kind Code:
A1
Abstract:
A pulse Doppler ultrahigh spectrum resolution imaging processing method, comprising: acquiring IQ signals respectively corresponding to N sampling points on each scanning line, and performing wall filtering processing on same in a fast time direction, so as to constitute an IQ signal wall filtering sequence corresponding to each scanning line (S1); respectively performing FFT transformation on each of the sampling points in the IQ signal wall filtering sequence sequentially in a slow time direction and the fast time direction, so as to acquire an energy distribution matrix of each of the sampling points on different frequency shifts (S2); acquiring a speed distribution matrix matching the energy distribution matrix (S3); and calling a speed sequence for displaying, and querying the speed distribution matrix and the energy distribution matrix matching the speed matrix in accordance with the speed sequence, so as to acquire an energy sequence corresponding to the speed sequence for final frequency spectrum displaying (S4).
