Abstract

The invention discloses a vehicle-mounted rotor wing unmanned aerial vehicle recovery guide system and method based on a millimeter wave radar. The system comprises a vehicle-mounted GPS system, a vehicle-mounted millimeter wave radar system, a vehicle-mounted rotor wing unmanned aerial vehicle recovery system, a power supply system and a central controller, wherein the vehicle-mounted GPS systemacquires the position of a vehicle in real time; a return instruction is sent to a rotor wing unmanned aerial vehicle flight control system through the central controller; whether the distance betweena rotor wing unmanned aerial vehicle and the vehicle reaches a landing threshold value or not is compared in real time; an electromagnetic wave signal is sent to the rotor wing unmanned aerial vehicle by the vehicle-mounted millimeter wave radar system; an echo signal reflected by the rotor wing unmanned aerial vehicle is received; the distance between the rotor wing unmanned aerial vehicle and the vehicle, the speed relative to the vehicle and pitching angle information are calculated; whether the distance between the rotor wing unmanned aerial vehicle and the vehicle reaches a recovery distance threshold value or not is compared in real time; and the vehicle-mounted unmanned aerial vehicle recovery system is started to finish the recovery of the rotor wing unmanned aerial vehicle. According to the guide system and method, the universality of a combat environment of the rotor wing unmanned aerial vehicle can be effectively improved, and autonomous landing and all-weather dynamic recovery of the rotor wing unmanned aerial vehicle are realized.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle recovery, in particular to a recovery guidance system and method for a vehicle-mounted rotor unmanned aerial vehicle based on millimeter wave radar. Background technique [0002] The vehicle-mounted rotor UAV is a combat model that uses land vehicles as base stations. It has combat capabilities such as reconnaissance, countermeasures, and battlefield dynamic control. It can adapt to the working environment, natural environment, and combat environment on land to the greatest extent. At present, the research and application of the recovery and guidance methods of the rotor UAV mainly include laser guidance, GPS guidance and TV tracking guidance. Among them, the core technology of laser guidance and TV tracking guidance is image processing technology, which compares the pre-stored pictures in the flight control system of the rotor UAV with the pictures taken by the onboard camera in real time t...
