| Abstract: | The problem of moving ship 3D imaging is investigated based on along track-cross track InSAR technology with three antennas.The range migration correction and image registration are introduced integrally.A new method of time-frequency analysis associate with interferometric processing technology is presented.The three images of the three antennas can be obtained by time-frequency analysis method in any azimuth time tk.Then the interferometric processing is applied to the three images.The scatterers spatial position in ship target can be extracted from interferometric phase.Three-dimensional imaging of moving ship targets can be achieved.The processing results of simulated data show the effectiveness of the presented method. |
