Abstract

The invention discloses an unmanned aerial vehicle networking device and method based on wide-area homogenized laser. The unmanned aerial vehicle networking device is composed of a system control module (1), a lifting type omnidirectional corner reflector (2) and a plurality of wide-area homogenization laser positioning communication units (3) which are arranged circumferentially, and can perform 360-degree omnidirectional coverage positioning communication on a communication target. The wide-area homogenization laser positioning communication unit (3) carries out positioning communication on a communication target based on a laser ranging and communication integrated technology, a large-field-angle wide-area homogenization laser is adopted to emit signals, and a large-view-field optical system is adopted to receive laser signals, so that inter-machine laser positioning communication is easier to establish and maintain, and the communication efficiency is improved. And the size and weight of the airborne laser communication system can be greatly reduced, so that the airborne laser communication system can be applied to small and medium-sized unmanned aerial vehicles. According to the unmanned aerial vehicle networking method, a plurality of one-way positioning communication loops with a long aerial vehicle as a center node are formed, and an unmanned aerial vehicle network capable of obtaining mutual positions of networked unmanned aerial vehicles in real time and interacting information in real time is established.
