Tracking of convoys by airborne STAP radar

In this contribution the problem of tracking convoys moving on the ground by means of airborne radar is discussed. A coherent radar with multi-channel array antenna is considered which makes clutter suppression by space-time adaptive processing (STAP) techniques possible. In addition, a technique to estimate the lateral length component of a convoy is used in addition to the conventional range measurement. In this way, knowledge about the full length vector of the convoy is obtained. In the second part of this paper we discuss how far the knowledge about the true convoy length can contribute to improving the tracking process.
