摘要: 为实现两飞行器在飞行过程中的正常通信,需建立一套通信区域的计算模型.基于空地无线数据链通信,从其实现正常通信的条件出发,考虑通信链路中的发射机、接收机、收发天线、传输空间及地球曲率、飞行器姿态角以及飞行器的空间位置关系等因素,分析研究了飞行器间无线数据链通信区域,建立了两飞行器间无线数据链通信区域的数学模型,包括天线、飞行高度、两飞行器空间位置关系、通信区域模型等.该模型已成功应用于某型号,为分析建立在无线数据链通信方式基础上的空地无线传输系统通信区域提供了参考,也适用于飞船、卫星等其它空空、空地无线数据通信系统.

Abstract: A mathematical model of communication region should be developed for realizing normal communication of two aircraft in flight. Based on the air-to-ground wireless datalink communication, the wireless datalink communication area between two aircraft was analyzed by considering the factors such as transmitters, receivers, send and receive antennas in communication datalink, transmission space and earth curvature, vehicle attitude angle and space positional relationship of aircrafts from implementing the normal communication conditions. A mathematical model of wireless datalink communication area between two aircraft was developed, including antennas, flight altitude, space positional relationship of two aircraft, communication area models and so on. The model has been successfully applied to a particular model; it provides a reference for analyzing air-to-ground wireless transmission system communication area based on the wireless datalink communication, and supplies for the spacecraft, satellite and other air-to-air, air-to-ground wireless data communications systems.
