Abstract

The invention discloses a sea clutter suppression method for an all-solid-state VTS radar. The sea clutter suppression method comprises the steps of: performing sea clutter suppression preprocessing on a radar echo signal; utilizing radar data processing control parameters to perform data processing on the radar echo signal after sea clutter suppression preprocessing, so as to obtain sample data of sea clutter; performing data mapping processing on the sample data of the sea clutter to obtain sea clutter data; utilizing the sea clutter data to perform sea clutter suppression processing on theradar echo signal after sea clutter suppression preprocessing; and performing interframe accumulation interpretation on the radar echo signal after sea clutter suppression processing to obtain targetecho information after sea clutter suppression processing. The sea clutter suppression method solves the problem of low precision of target signal detection, improves the precision of target parameterjudgment, reduces the risk that the sea clutter is misjudged to be the target, and provides a reliable data foundation for subsequent target extraction.

Description

technical field [0001] The invention relates to the technical field of sea clutter suppression for all-solid-state VTS radars, in particular to a sea clutter suppression method for all-solid-state VTS radars. Background technique [0002] VTS radar is an information perception device for vessel traffic management services. The basic tasks of VTS radar include: 1. Perceive the position and movement data of ship targets; 2. Perceive the position data of buoys, lighthouses or other fixed targets; 3. Perceive pre-ship SART Signal. However, the existence of sea clutter seriously affects the performance of all-solid-state VTS radar for sea detection. Therefore, improving the sea clutter suppression performance of all-solid-state VTS radar has great influence on the design of all-solid-state VTS radar system, radar signal processing and radar detection of sea targets. has important practical significance. [0003] The distribution characteristics of sea clutter are complex. It is...
