Problems solved by technology

[0004] The existing UAV security defense system and related technologies use commercial UAVs as the detection and defense objects, and the frequency range covered is the ISM frequency band. The defense system covers a narrow frequency range and cannot effectively detect and defend modified UAVs. In addition, the existing countermeasure system uses frequency sweep to suppress interference, waste energy, and easily cause adverse environmental impact

Abstract

The invention provides a detection and countermeasure method for a cloud intelligent low-altitude intrusion linkage defense system, including a cloud computing center, a full-band passive detection system, and a full-band countermeasure system. The full-band passive detection system includes multiple detection channels. Detect radio frequency signals in all frequency bands, detect the presence or absence of radio frequency signals, determine the parameters of radio frequency signals, sort out intrusion signals, pair the intrusion signals detected by multiple detection channels, and determine the airspace attributes of the intrusion target ; Under the guidance of the control command or the full-band passive detection system, the full-band countermeasure system generates countermeasures corresponding to the characteristics of the intruding target to complete the intelligent countermeasures against low-altitude intruders. The invention realizes effective detection and countermeasures against low-altitude intruders in all frequency bands, has no blind areas in the frequency domain, no blind frequency sweeping interference, does not waste energy, and causes unfavorable environmental hazards, and effectively realizes the Security protection for stations, large commercial venues, private places and sensitive areas.

Description

technical field [0001] The present invention belongs to the technical field of low-altitude security defense, and specifically relates to a cloud-intelligent low-altitude intrusion linkage defense system for security protection of government agencies, military facilities, energy reserves / stations, large commercial venues, private places and sensitive areas. Detection and Countermeasures. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but it is equipped with autopilot, program control device and other equipment. Radar and other equipment, for tracking, positioning, remote control, telemetry and digital transmission, can take off like an ordinary plane under radio control or launch it with a booster rocket, or it can be brought into the air by the mother plane for flight. When it is recovered, it can be used It automatically lands in the same way as an ord...
