Tracking of multiple ground targets with adaptive monopulse radar. Part I: The sensor

In this contribution and in companion paper [1] aspects of ground target tracking by means of airborne radar are discussed. The radar sensor consists of a multichannel array antenna enabling space-time adaptive processing (STAP) for clutter rejection, and angle and Doppler monopulse estimation. Both the STAP and adaptive monopulse algorithms are described and the aptitude for monopulse estimation with different processor architectures is discussed. Results for a typical multiple-target scenario are presented.
