Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Please refer to figure 1 and figure 2 , figure 1 It is a structural diagram of the airborne troops massing communication system; figure 2 It is a structural schematic diagram of the direction finding device of the present invention. The airborne troops massing communication system 100 includes a central control device 1 and 50 to 100 direction finding devices 2. The central control device 1 continuously transmits radio signals to the direction finding device 2. The direction finding device 2 transmits radio signals according to the received radio signals. The signal is used to measure the direction angle between the central control device 1 and the direction-finding device 2 , and at the same time, the central control device 1 issues instructions to the direction-finding device 2 .

[0025] The direction finding device 2 is used to receive ...

Abstract

A direction-finding device is used to transmit radio signal uninterruptedly in the control device of a receiving center, and comprises a first radio frequency receiving unit and a second radio frequency receiving unit which are symmetrical, a first antenna and a second antenna respectively connected with the first radio frequency receiving unit and the second radio frequency receiving unit, a frequency synthesizer, a local oscillation circuit, a baseband signal processing unit and a control unit, wherein, the signal, which is received by the first antenna and the second antenna and is processed by the first radio frequency receiving unit and the second radio frequency receiving unit, is provided to the frequency synthesizer, the local oscillation circuit and the baseband signal processingunit; the processed signal is provided to the control unit; finally, the control unit, according to the field intensity signal of the first radio frequency receiving unit and the second radio frequency receiving unit, calculates the direction angle between the control device of the center and the direction-finding device. The invention can realize remote positioning and orientation measurement inthe absence of a satellite positioning system along with high measurement precision and strong diffraction capability. Moreover, the invention also provides a direction-finding method.

Description

【Technical field】 [0001] The invention relates to the communication field, in particular to a communication system and method for airborne troop assembly. 【Background technique】 [0002] At present, the general navigation and positioning method is to use satellite positioning systems, including the Global Positioning System (Global Position System, GPS) of the United States, the Global Navigation Satellite System (Global Navigation Satellite System, GLONASS) of Russia and the navigation and communication satellites of the European Space Agency. (Navigation Communication Satellites, NAVSAT) system. [0003] In the field of military operations, the tactical assembly of foreign airborne troops mainly uses a handheld walkie-talkie integrated with a GPS receiver. The handheld walkie-talkie does not distinguish between commanders and ordinary team members, but can transmit the position data of team members to each other, so as to achieve peer-to-peer positioning, and the position...
