Adaptive monopluse with STAP

Monopulse is a well known technique for high accuracy estimation of target parameters such as azimuth and elevation as well as the radial velocity. In conjunction with an adaptive processor for cancellation of interference one obtains so called adaptive monopulse. Interference may be either jamming or clutter or both. In this contribution some properties of adaptive monopulse applied in a clutter environment is discussed. We focus on an airborne radar scenario so that the adaptive monopulse includes a space-time adaptive processor (STAP). Several different STAP architectures are compared with respect to their aptitude for target parameter estimation
