Abstract
Synthetic aperture radar (SAR) is an active, all-weather capable system to provide the capability to map the ground with high resolution and is used in both civilian and military applications. Moving targets with respect to the stationary background cause smeared and ill-positioned images. Detection and imaging of moving targets in SAR signals are necessary. We propose the method that combined the ridges of the short-time Fourier transform (STFT) and Radon transform (RT) to detect moving targets. Processing steps of this method and simulated results are given in detail. Simulation results show this method can detect moving targets and estimate its parameters in noise case effectively.
