Abstract

Triple-Channel SAR system can detect moving target, and estimate its range velocity. However, the problems of blind velocity and velocity ambiguity still exit. To resolve these problems, Triple-Channel Multi-Input Multi-Output SAR (Triple-Channel MIMO-SAR) system, with a displaced phase center antenna (DPCA) and interferometry method based on matched Fourier Transform (MFT), is proposed in this paper, which could combine detection and estimation results of different working frequencies and obtain accurate Doppler frequency modulated rate estimation. Using this method, we can not only detect moving target and estimate its range velocity, but also resolve the problems of blind velocity and velocity ambiguity and get accurate azimuth velocity estimation. The effectiveness of this approach is validated by the computer simulation results.
