Adaptive nullsteering of main lobe jamming; analysis of the ARTIST trials

Abstract

The paper considers the effectiveness of adaptive nullsteering in main lobe jamming scenarios. Four variants of algorithms are evaluated using data that has been gathered experimentally with an eight element array radar operating at C-band. The measurements were conducted in a coastal environment. Compared to fixed beamforming, an improved detection capability is clearly demonstrated. Furthermore, clutter suppression prior to weighting yields further improvements under adverse weather and sea state conditions.
