Radar Clutter Suppression System

摘要

Sidelobe suppression methods and systems for use in processing radar video streams generated by rotational radar antenna scanners. The sidelobe suppression methods function in parallel with traditional Sensitivity Control (SC) processing by selectively reducing sensitivity where necessary depending on sidelobe suppression schemes that can be either directional, omni-directional (non-directional), or a combination of these.

1. A method of suppressing sidelobe clutter for a radar signal processing system that receives a radar video stream from a radar antenna scanner and applies Sensitivity Control (SC) processing to the radar video stream based on an SC threshold profile that defines an echo return intensity threshold over range, comprising:
determining the peak echo return intensity level (herein: peak return level) at each range based on radar video stream representing a full scanner sweep; and selectively modifying the SC threshold profile based on the determined peak echo return intensity levels from the full scanner sweep.
