Abstract :
A novel algorithm is proposed for separating multiple moving targets in radar images in the slow time-range domain. Target discrimination is based on an image texture angle that is related to the target´s instantaneous velocity. The algorithm efficiency has been successfully verified for targets with variable velocities.
