Abstract

Abstract

Sea clutter is one of the main limiting factors influencing the target detection performance of nautical radars, and its physical mechanism at low grazing angles has been widely studied. Due to the difference in the generation mechanism, it is difficult to adopt directly the existing diversified low clutter angle sea clutter model and characteristic conclusions in the cognitive study of the sea clutter characteristics under large grazing angle.The study of sea clutter characteristics under large grazing angles is still extremely complicated and has to be systematic. Based on the commonly used data, this paper reviews and summarizes the research developments in sea clutter at large grazing angles. It concentrates on the properties that are of most interest for target detection at large grazing angles: the characteristics, modeling methods and detection technology algorithms. The main research results are concluded and the development direction of the technology is prospected.
- Target detection,
