Abstract

The invention relates to the field of radio, aims at solving the problems of flight path measurement of a low-slow-small unmanned aerial vehicle target and beam synchronous scanning of multi-static radar, and discloses a low-slow-small unmanned aerial vehicle flight path measurement system and method. The system comprises monitoring equipment, a transmitting station, receiving stations, a data processing center and data transmission links. The number M of the monitoring equipment is greater than or equal to 2 and the monitoring equipment is used for measuring the radiation signal and the direction of the unmanned aerial vehicle. The data processing center determines the target area of the unmanned aerial vehicle and guides the transmitting station and the receiving stations to synchronously point to the target area. The transmitting station and the receiving stations are respectively configured in the middle and the periphery of a protective area, wherein one set is configured in the middle and at least two sets are configured at the periphery. The receiving stations only receive and process the echo signal of the target area. The data transmission links complete transmission of data, command and reference signals. The low-slow-small unmanned aerial vehicle flight path measurement system and method can be applied to the airport clearance protective area and the large oil depots and other key protective areas.

Description

technical field [0001] The invention relates to the field of radio, in particular to a track measurement system and method for a low-slow small unmanned aerial vehicle. Background technique [0002] In recent years, the number of various drones has increased rapidly, and potential hazards have gradually emerged. For example, there have been frequent incidents of drones interfering with civil aviation flights in airport clearance protection areas, causing flight diversions, return flights, or delays, seriously threatening the flight of civil aviation airliners. Safety. In order to effectively deal with the growing real threat of various drones, it is urgent to measure the track of drones in the protected area, so as to accurately judge the threat level of drones and take corresponding countermeasures in time. [0003] Multiple sets of radio detection equipment can locate UAVs, but the accuracy is usually low, and the application occasions are limited. At present, radar detec...
