摘要

这项工作的目的是研究无人机(UAV)无线通信的空对空(A2A)信道建模的地面反射建模案例研究。我们考虑2.4 GHz标准的物联网(IoT) WiFi模块与发射器Tx- UAV和接收器Rx-UAV一起启用。采用自由空间路径损耗(FSPL)模型、空对空双射线(A2AT-R)模型和改进的对数距离路径损耗模型来处理接收信号强度指标(RSSI)和路径损耗特性。测量结果表明，WiFi模块的功率约束极限在Rx-UAV高度10 m处为1级，接收灵敏度限制在-95 dBm。结果表明，地面反射路径损失的影响主要表现在1 ~ 3 m Rx-UAV高度，与A2AT-R模型相关，与改进的Log- distance模型相关结果在4 m Rx-UAV高度以上。

A Study of A2A Channel Modeling for Small UAV-Enabled Wireless Communication

The objective of this work is to study the ground reflection modeling case study of air-to-air (A2A) channel modeling for an unmanned aerial vehicle (UAV)-enabled wireless communications. We consider the Internet of Things (IoT) WiFi modules at 2.4 GHz standard enabled with the transmitter Tx- UAV and the receiver Rx-UAV. The received signal strength indicator (RSSI) and path loss characteristics are addressed by using the free space path loss (FSPL) model, air-to-air two- ray (A2AT-R) model, and the modified Log-distance path loss model. The measurement results indicated that the limit of power constraint of WiFi modules was a level at 10 m Rx-UAV altitude, and the received sensitivity was limited at -95 dBm. It is shown that the impact of ground reflection path loss was characterized at 1–3 m Rx-Uavaltitudes which are accordingly related to the A2AT-R model and the relative resulting with the modified Log- distance model above 4 m Rx-UAV altitudes.
