Low slow small prevention and control system and method based on data chain detection and countering

Abstract

The invention discloses a low slow small prevention and control system and method based on data chain detection and countering. The system and method are mainly used for solving the problem that whena low-altitude slow-speed small target unmanned aerial vehicle (hereinafter referred to as a'low slow small aircraft') appears in an urban complex environment, due to shielding of buildings and various buildings, radar detection equipment, visible light / infrared equipment and the like cannot effectively find and identify targets, and a laser interception mode and a net bomb capturing mode cannot play a role. According to the method and the system, a multipoint networking mode of radio monitoring is adopted; the method is specially used for detecting a data chain of a low slow small aircraft; amulti-point layout mode in a networking area is utilized to describe the navigation track of the aircraft, refined processing is carried out on a tested data chain point by point, and when the low slow small aircraft enters a forbidden airspace, the flight of the aircraft is destroyed by adopting a same-frequency suppression interference and GPS signal area spoofing manner, thereby achieving theprevention and control of the low slow small aircraft in an urban complex environment.

Description

technical field [0001] The present invention relates to the fields of communication data link technology, unmanned aerial vehicle system technology, electronic interference and anti-interference technology, networking optimization strategy, etc. In the case that visible light / infrared equipment and radar detection equipment cannot be effectively detected, and jamming equipment and net bomb capture methods cannot play a role due to the occlusion of objects, use a reasonable network layout to discover data link information and target navigation information and communication data. Methods and systems for detecting and countering low-slow and small aircraft targets, such as spoofing and suppression of chain information. Background technique [0002] Low-slow small aircraft refers to low-altitude, slow-speed, small target aircraft with a flight altitude of less than 1,000 meters, a speed of less than 200 km / h, and a radar reflection area of ​​less than 2 square meters. With the ...

AI Technical Summary

Problems solved by technology

The current prevention and control systems for low-slow and small aircraft often use composite detection methods such as photoelectricity, radar, and acoustic detection, and composite countermeasures such as laser damage, net-catching missiles, and radio interference. , can have the functions required by the indicators, but cannot exert its prevention and control effect in the complex urban environment
