Abstract

The invention discloses a device and a method for predicting a ground target motion trail of an unmanned aerial vehicle. A moving target data acquisition module acquires data of a ground moving target through an onboard sensor system in an onboard device of the unmanned aerial vehicle. A moving target data processing module converts a ground moving target motion trail three-dimensional polar coordinate into a three-dimensional rectangular coordinate, performs standardization processing on target trail data and the performs analytical prediction. A moving target trail generating module invokes a ground moving target trail predicting method in a predicting method library, performs analytical prediction on trail standardization data of the moving target and generates a prediction result. A moving target trail recommendation module calculates the recommendation level of the current moving target trail prediction result according to the standardization data and the prediction result. The device and the method for predicting the ground target motion trail of the unmanned aerial vehicle have the advantages of being capable of effectively predicting the ground target motion trail and providing reliable information for an unmanned aerial vehicle mission planning system and the like.

Description

technical field [0001] The invention relates to a device and method for unmanned aerial vehicles to predict the trajectory of ground targets. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft that can be controlled autonomously by radio remote control or by using its own control system. The self-contained control system of the UAV includes navigation flight control system, program control system, power and power supply and other equipment. The ground control center can track, locate, remote control, telemetry and digital transmission through data link and other equipment. Compared with manned aircraft, drones have the advantages of convenience, small size, low cost, and adaptability to various flight environment requirements, so they can be widely used in air tracking, investigation, surveillance, communication, rescue, anti-submarine, electronic interference, etc. [0003] At present, the use of drones is limited to specific ta...
