Channel Modeling and Characterization of Typical Flight Scenarios of Low-Altitude Unmanned Aerial Vehicles

In this paper, a channel measurement system suitable for typical flight scenarios of low-altitude unmanned aerial vehicles (UAVs) is constructed, and a channel measurement algorithm is proposed. Based on this system, the channels of three typical flight scenarios of UAVs are measured, including two line-of-sight (LOS) scenarios and one non-line-of-sight (NLOS) scenario. Then, the channel measurement results are statistically analyzed, and the channel characteristics are analyzed. Finally, the channel model of these typical scenarios is constructed, and the typical parameters such as root mean square delay spread (RMS-DS) and Rice factor are given.
