Long-Term Integration Algorithm and System Design Using the Stepped-Frequency Signal

A novel algorithm of multi-burst stepped-frequency signal co-processing are proposed, from which the high resolution in both range and velocity profile of moving targets can be achieved. A fast keystone transform is presented to remove the range migration between the bursts causing by the long-term integration, which is of efficiency to implementation. A real-time signal processing system is designed to process multiburst stepped-frequency signal in real-time and employ velocity compensation algorithm based on keystone transform.
