SAR imaging of moving targets based on second order Match Fourier Transform

Synthetic Aperture Radar (SAR) imaging of moving targets is important and difficult with existing airborne SAR technique, and the traditional SAR imaging algorithm can not achieve the desired results. In this paper, a new SAR imaging algorithm based on the second order Match Fourier Transform (MFT) is presented according to the characteristic of the received signal for moving targets. This method has effective focusing ability for moving targets. The simulated results demonstrate the validity of this algorithm.
