Ground target tracking with adaptive monopulse radar
Abstract
Tracking of ground moving vehicles using airborne or space-based radar is basic for producing a recognized ground picture as well as for analyzing traffic flows, identifying sources and sinks of traffic, or detecting lines of communication, e.g. The considered radar sensor is based on a multichannel array antenna to enable the use of space-time adaptive processing (STAP) for clutter rejection, and an angle and Doppler monopulse procedure. Firstly, the STAP and the adaptive monopulse algorithms are described and some angle and velocity estimation results are presented for a typical radar-target scenario. Secondly, aspects of a GMTI tracking algorithm for processing the STAP-monopulse estimates are described and some typical tracking results are given. Special emphasis is placed on suitable modeling of the radar characteristics within the tracker
