Abstract

We present a novel method for ground moving target detection and imaging using a SAR system transmitting ultra-narrowband continuous waveforms. We develop a new forward model that relates the velocity as well as reflectivity information at each location to a correlated received signal. We reconstruct moving target images by a filtered-backprojection method. We use the image contrast as a metric to detect moving targets and to determine their velocities. The method results in well-focused reflectivity images of moving targets and their velocity estimates regardless of the target location, speed, and velocity direction. We present numerical experiments to verify our method.
