Unmanned aerial vehicle control method for target continuous observation

Abstract

The invention provides an unmanned aerial vehicle control method for target continuous observation. The method comprises the following steps: unmanned aerial vehicle, passive detection equipment and target indication information are acquired, and the position of an unmanned aerial vehicle is calculated; an unmanned aerial vehicle and target connection line is calculated; intersection points of theunmanned aerial vehicle and target connection line and the edge of a target scattering area are calculated, and the intersection points in the unmanned aerial vehicle sight direction are taken as traction points; according to the placement position of passive detection equipment on the unmanned aerial vehicle, the fly-around radius is determined, and an unmanned aerial vehicle control instructionis generated. The method is simple and feasible, the algorithm calculation amount is small, the unmanned aerial vehicle control instruction of fly-around center + fly-around radius is generated, theinput forms of most of unmanned aerial vehicle companies in the existing market are met, the unmanned aerial vehicle companies do not need to greatly change the flight control program, and the verification requirement of passive guidance is met.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle control, and in particular relates to an unmanned aerial vehicle control method for continuous target observation. Background technique [0002] In the research of passive guidance technology, the verification of passive guidance process is usually carried out by means of helicopter flying and hardware-in-the-loop simulation. With the development of UAV technology and the improvement of equipment miniaturization capabilities, UAV flying tests can be used to verify passive detection equipment and guidance laws. This test technology is more effective in the inspection of complex guidance processes. Advantages are particularly important in the verification of cooperative guidance algorithms. [0003] During the drone flight test, the test is usually carried out in cooperation with the drone company. Before the test, the passive detection equipment needs to be installed on the UAV, a...

Problems solved by technology

However, the UAV company needs to open up the control authority and make substantial changes to the existing flight control program; due to delay considerations, only the on-board control method can be adopted, and ground control cannot be used; the coupling of disciplines is large, and it is difficult for UAV companies to carry out instructions. Inspection, it is prone to crash accidents; after the drone fails, it is difficult t
