Paper Abstract

A method for moving-target imaging in dual-channel SAR system based on space-time-frequency signal processing is studied. In space-time domain, adaptive sliding-window processing method is applied to get high output signal to noise ratio by dual-channel clutter suppression. In time-frequency domain, modified discrete Chirp-Fourier transformation is applied to get Doppler modulation frequency parameters. Range migration is solved by Keystone transformation. Azimuth velocity accuracy is improved by phase compensation. Parameter decoupling is solved by channel phase deviation. A lot of simulation experiments verify the validity of the proposed method.
