Unmanned ship navigation collision avoidance radar detecting method

Abstract

The invention discloses an unmanned ship navigation collision avoidance radar detecting method. The method comprises the following steps that omnibearing target searching is carried out on an observed sea area through a radar antenna and a transceiver, reflection echoes of a target are received, and target original video signals with clutter are obtained after amplification frequency conversion detection; the original video signals are sent to a signal collecting module through a signal interface module for A / D conversion, and target original digital video signals with clutter are obtained; software-oriented trace point extraction, signal processing, clutter rejection and target detecting tracking data processing are automatically carried out on the target original digital video signals through a ruggedized computer, meanwhile, signals of a gyrocompass, a log, a GPS, an AIS and an optoelectronic device of the ship are received, moving platform motion compensation and target fusion are carried out, various on-sea targets are captured and tracked, a target track is set up, and then tracking detection is carried out. Comprehensive detection, tracking and recognition of the unmanned ship in the complex sea condition on multiple batches of targets on the sea are achieved.

Description

technical field [0001] The invention relates to the technical field of a comprehensive detection, tracking and identification system for a sea target by a manned ship, in particular to a radar detection method for unmanned ship navigation and collision avoidance. Background technique [0002] The simple navigation radars used by existing small ships have weak detection capabilities, and generally can only manually track 20 batches of targets at most. Small targets cannot be detected under clutter conditions, so they cannot meet the requirements of unmanned ship navigation and collision avoidance. Based on the small ship navigation radar antenna and transceiver unit, we have conducted a lot of research on the detection and tracking technology of maneuvering small targets, focusing on improving signal processing technology, clutter suppression technology and detection and tracking algorithms, greatly improving the clutter conditions Capable of detecting small targets, fully au...
