A distributed detection system and detection method of a base station type small unmanned aerial vehicle

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a distributed detection system and detection method of a base station type small unmanned aerial vehicle. In the present invention, the front end of the general radio frequency array is responsible for sending detection signals to scan and detect targets in the action area, and processing the corresponding echo signals, and sending the processing results back to the comprehensive information processing device; the comprehensive information processing device Coordinate the distribution of radar detection frequencies of each node and receive the echo signals of the detection signals of each active area from the front end of the general radio frequency array, perform comprehensive processing, obtain the size, distance, speed, position, and orientation information of the target, and plot it on the electronic map and display; the supporting equipment provides power supply and communication equipment for the general radio frequency array front-end and comprehensive information processing equipment. The invention solves the problems in the existing products that it is difficult to effectively cover the occlusion area, the transmission power of the equipment is limited, and the cost of the radar equipment is high, and satisfies the detection and control requirements for "low, slow and small" targets in tasks such as defense of key points, anti-terrorism and stability maintenance.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a distributed detection system and detection method of a base station type small unmanned aerial vehicle. Background technique [0002] At present, there are related technologies and research results on the detection, identification and tracking capabilities of "low, slow and small" UAVs at home and abroad. For example, the United States, Russia, the United Kingdom, France, Israel and Italy all have corresponding products, such as the United States R8SS -3D drone detection radar, Italian Black Knight drone detection radar, France 500 / 1000 safety radar, ELVIRA drone detection radar in the Netherlands, A400 series radar in the UK, etc. [0003] However, the existing UAV radar detection products mainly have the following problems: (1) Under complex terrain conditions such as cities, the occlusion is serious, and it is difficult to effectively cover the...
