Modelling of the Impact of Antenna Rotation on Clutter Improvement Factor in Naval Radars Operating in Littoral Environments

Naval operations are increasingly conducted in the littoral environment, requiring extremely high clutter improvement factors (CIF) to be achieved to enable small target detection. This paper describes a littoral clutter model to support synthetic baseband radar data generation and examines the impact of antenna rotation on the clutter filtering required to achieve these high clutter improvement factors. The impact of this analysis on waveform and signal processing design for future naval radars is discussed.
