两飞行器间无线通信区域的仿真

The Simulation of Wireless Communication Area Between Two Aerocrafts

文章对自由空间传播损耗能量逐渐消弱的原因进行了分析,由于地球的遮挡将可能使两飞行器无法保持正常通信,从而限定飞行器最低飞行高度;还对无线数字通信链路和两飞行器的相对位置关系进行了分析。对某一确定的距离,均存在一定的角度范围,在某些特定条件下两飞行器间可实现正常通信的通信区域进行建模,并仿真了两飞行器间的通信区域。

The paper analyses the reason why free-space propagation loss lets energy gradually weaken.Two aeroerafts can not keep normal communication owing to earth shelter from electromagnetic wave,so it limits the lowest height of the two aerocrafts. It analyses wireless the digital communication link and positional relationship of two aerocrafts.Between the two aerocrafts normal communication to model communication area can be realized in a certain distance and in a certain angle,and have simulated the communication area between the two aerocrafts.
