Abstract

A new type of beamformer has been proposed which uses dynamic clutter cancellation with the help of an auxiliary beam in an external clutter limited scenario like shipborne HF Surface Wave Radar (SWR). The beamformer is compact, ensures reasonable azimuth resolution and unlike the conventional beamformers the azimuth resolution decays gracefully in low Signal to Clutter power Ratio (SCR) scenarios. It has been demonstrated that a 7 element beamformer can detect targets with Radar Cross Section (RCS) of 30 dBsm and above with an angular resolution of 4.6°.
