Space-Time Adaptive Monopulse Processing for Airborne Radar in Non-homogeneous Environments

Array Pattern Distortion and Remedies in Space–Time Adaptive Processing for Airborne Radar

Space–time adaptive processing (STAP) for airborne early warning radar has been a very active area of research since the late 1980’s. An airborne rectangular planar array antenna is usually configured into subarrays and then partial adaptive processing is applied to the outputs of these subarrays. In practice, three kinds of errors are often encountered, i.e., the array gain and phase errors ex...

A Space/Fast-Time Adaptive Monopulse Technique

Mainbeam jamming poses a particularly difficult challenge for conventional monopulse radars. In such cases spatially adaptive processing provides some interference suppression when the target and jammer are not exactly coaligned. However, as the target angle approaches that of the jammer, mitigation performance is increasingly hampered and distortions are introduced into the resulting beam patt...

An adaptive monopulse processor for angle estimation in a mainbeam jamming and coherent interference scenario

Mainbeam jamming poses a particularly diicult challenge for conventional monopulse radars. In such cases spatially adaptive processing provides some interference suppression when the target and jammer are not exactly co-aligned, but the resulting array pattern is too distorted to be suitable for monopulse processing. The presence of coherent multi-path in the form of terrain scattered interfere...

Knowledge based adaptive processing for ground moving target indication

This paper presents a preliminary knowledge based approach to Space-Time Adaptive Processing (STAP) for ground moving target indication from an airborne platform. The KB-processor accounts for practical aspects of adaptive processing, including detection and processing of non-homogeneous data, appropriate selection of training data, and accounting for array effects such as mutual coupling and c...
