Clutter modelling for space-time adaptive processing

The presence of clutter can be highly detrimental to detection of targets. STAP attempts to alleviate the problem by exploiting angle-Doppler inter-relationships to suppress clutter. The simulation of clutter data that is suitable for the application of STAP is considered. Examples of clutter generated using the ELMBAARC program in bistatic applications and forward facing and sideways facing monostatic applications are provided. Modelling of internal clutter motion is considered, together with its effect on the clutter domain in angle-Doppler space.
