Abstract

The present invention provides a method for flexibly defining composite interference through external instructions, including four parts: composite navigation interference, forwarding interference, modulation interference, and interference synthesis. According to the instructions, the composite navigation interference module generates satellite navigation signals, and the forwarding interference module generates forwarding interference signals. . The modulation jamming module generates a modulated jamming signal, and synthesizes it into a composite jamming signal according to the regulations of the instruction, thereby forming a comprehensive jamming capability for low-altitude intruder navigation, remote control and image transmission. The invention can flexibly define composite interference through external instructions, thereby effectively counteracting the full frequency range of low-altitude intruders, without frequency domain blind spots, without blind frequency scanning interference, without wasting energy, without causing adverse environmental hazards, and effectively realizing Security protection for government agencies, military installations, energy reserves / stations, large commercial venues, private places and sensitive areas.

Description

technical field [0001] The invention belongs to the technical field of low-altitude security defense, and in particular relates to a system for flexibly defining composite interference through external instructions for the security protection of government agencies, military facilities, energy storage warehouses / stations, large-scale commercial venues, private places and sensitive areas. 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 a...
