Single-carrier-frequency-band full-duplex measurement and control communication method of unmanned aerial vehicle of target use type

Abstract

The invention discloses a single-carrier-frequency-band full-duplex measurement and control communication method of an unmanned aerial vehicle of a target use type. The method comprises the followingsteps: 1) initializing a ground control station and an airborne measurement and control terminal, and enabling the ground control station and the airborne measurement and control terminal to be in receiving status; and 2) establishing a communication link between the ground control station and the airborne measurement and control terminal by a single data radio in the ground control station and asingle data radio in the airborne measurement and control terminal through a TDD (Time Division Duplex) protocol used for communication and transmission, wherein the TDD protocol used for communication and transmission includes a TDD protocol frame structure, TDD protocol frame synchronization and TDD protocol communication realization. The method enables the two communication parties to be alternately configured to the receiving status or sending status to complete duplex communication by means of a TDD manner, only needs to occupy a single carrier frequency band in wireless communication, and is a low-cost and generalized single-carrier-frequency-band full-duplex measurement and control communication method.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle measurement and control communication, in particular to a single-carrier frequency band full-duplex measurement and control communication method for a target type unmanned aerial vehicle. Background technique [0002] Target drones (referred to as target drones) are mainly aimed at manned aircraft such as fighter jets and bombers, as well as aviation aircraft such as cruise missiles and drones, and simulate their flight performance such as altitude, speed and maneuverability, as well as radar reflection characteristics and infrared radiation characteristics. External characteristics, used for airborne and ground air defense detection systems, air defense artillery, air-to-air or surface-to-air missiles and other air defense weapon systems, functional performance tests, tactical and technical index assessments, or troop training and exercises, etc. [0003] The measurement and contr...

AI Technical Summary

Problems solved by technology

The sending and receiving channels all need their own hardware support, the number of devices increases, and the cost also increases; the sending and receiving channels need to be isolated, which increases the cost of equipment;

[0010] (2) The versatility of the FDD system is poor, and generally requires the support of special communication equipment, and the TDD system can be realized by using general communication equipment, such as digital radio stations;

[0011] (3) The FDD method needs to use paired frequencies, and the frequency utilization rate is low, while the TDD method can use various frequency resources;

[0012] (4) The FDD method has poor support for asymmetric data transmission
