Cloud intelligent low-altitude intrusion linkage defense system and method

Abstract

The invention provides a cloud intelligent low-altitude intrusion linkage defense system and method. The system comprises a cloud computing center, a full-band passive detection system and a full-bandcountering system; the full-band passive detection system comprises a plurality of detection channels, detects full-band radio frequency signals, detects the presence or absence of the radio frequency signals, determines the parameters of the radio frequency signals, sorts intrusive signals, pairs the intrusive signals detected by the detection channels, and determines the spatial domain attribute of an intrusive target. Ander the guidance of the control instruction or the full-band passive detection system, the full-band countering system generates countering signals corresponding to the intruding target characteristics, and intelligent countering of the low-altitude intruding object is completed. According to the invention, full-band effective detection and countering of low-altitude intrusions can be realized, a frequency domain blind area is avoided, blind frequency sweeping interference is avoided, energy is not wasted, adverse environmental hazards are avoided, and safety protection of government agencies, military facilities, energy storage warehouses / stations, large-scale commercial venues, private places and sensitive areas is effectively realized.

Description

technical field [0001] The invention belongs to the technical field of low-altitude security defense, and specifically relates to a cloud-intelligent low-altitude intrusion linkage defense system used for security protection of government agencies, military facilities, energy reserves / stations, large commercial venues, private places and sensitive areas and method. 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 ordinary aircraft, and can...

AI Technical Summary

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
