Maneuvering photoelectric detection and identification system for low, slow and small targets

Abstract

The invention discloses a maneuvering photoelectric detection and identification system for low, slow and small targets, which comprises an optical detection subsystem, a photoelectric parallel processing and identification subsystem and a servo subsystem, and is characterized in that the optical detection subsystem and the photoelectric parallel processing and identification subsystem are erected on the servo subsystem, and the servo subsystem is carried on a mounting platform of a carrier vehicle, the optical detection subsystem is used for collecting multiband optical information from a target and a background; the photoelectric parallel processing identification subsystem comprises a multiband image co-processing module and an information processing master control module, and each band co-processing module is used for carrying out single-frame detection identification on a target according to the image information of the corresponding band; the information processing master control module is used for performing multi-frame detection and identification on a target by adopting a JPEG image compression mode and a track association and multi-frame fusion mode; and the servo subsystem is used for completing target tracking according to the multi-frame detection identification result. The method is high in detection and recognition accuracy, high in maneuverability and capable of performing long-distance detection on a target.

Description

technical field [0001] The invention belongs to the technical field of aircraft detection, and more specifically relates to a mobile photoelectric detection and identification system for low, slow and small targets. Background technique [0002] In recent years, the further development and popularization of unmanned aerial vehicle and small aircraft technology have brought about irregular use, so that in some special scenarios, various typical aerial unmanned aerial vehicles, small aircraft and air balloons will affect us. People and property pose a serious threat, such as airport airspace security. [0003] At present, the detection and identification system for early warning of low, slow and small targets in the air is mainly ground-based. Because of the small reflection area of ​​typical low-slow and small-target radars in the air, it is difficult for ground-based radars to realize low-slow and small targets in the air due to the influence of low-altitude background clutt...

AI Technical Summary

Problems solved by technology

However, the existing ground-based photoelectric detection equipment mainly uses single-band infrared detection or dual-band detection to capture or identify targets, and domestic and foreign detection platforms are mainly fixed at specific locations to detect and identify targets. Due to the shortcomings of low detection rate and high false alarm rate, it is impossible to realize target detection and recognition under long-distance conditions, and it does not have the situational awareness capability of large-scale scenes
