Three-dimensional display and dead zone determining method of ground received electromagnetic signals of unmanned aerial vehicle

Abstract

The invention discloses three-dimensional display and dead zone determining method of ground received electromagnetic signals of an unmanned aerial vehicle. The three-dimensional display and dead zone determining method comprises the following steps: firstly, reading downlink data of a communication data chain in a network data reading manner, extracting the electromagnetic signal strength in an area near a ground receiving station from the downlink data, and screening and pre-processing data; then, performing unit modelling and attribute definition of a three-dimensional visual display model according to the receiving position and the numerical value of the data; finally, loading the three-dimensional visual operation of the data in different display lists according to a flight forward journey of the unmanned aerial vehicle by utilizing a computer graphic technology so as to realize three-dimensional visual display of the data; and determining the position of a communication dead zone by using a threshold value judging method, and adjusting the direction of a route so as to obtain the best planned route. According to the invention, the electromagnetic signal strength of the ground receiving end in the flight process of the unmanned aerial vehicle can be displayed dynamically in real time, and therefore, the method disclosed by the invention is applicable to monitoring chain information under multiple links and multiple channels and planning the route.

Description

technical field [0001] The invention belongs to the technical field of command and control of unmanned aerial vehicles, relates to the fields of computer graphics, electromagnetic environment, etc., and specifically refers to a three-dimensional display and communication blind area determination method for realizing electromagnetic signals received by unmanned aerial vehicles on the ground. Background technique [0002] With its accurate, efficient and flexible reconnaissance, interference, search and combat capabilities in irregular conditions, unmanned aircraft play a significant role in modern warfare. The ground station is the command and control center of the UAV system, and the UAV telemetry and remote control ground station is called the "nerve center" of the entire UAV system, which plays a very important role in the normal operation of the system. Therefore, the UAV has the disadvantage of single point failure, that is, once the ground station loses the normal link ...
