Measured and RT-based Air-to-Ground Channel Dataset (CIR) under Urban Scenarios

Air-to-ground (A2G) channels play a pivotal role in reliable communications between drone and ground terminal. A2G channel modeling is a hot topic, however there is little measurement data in real scenarios for model validation and comparison.
We have conducted channel measurements in urban scenario at the 3.6 GHz band with a bandwidth of 61.44 MHz. The antennas for both the Tx and Rx are replaced by dipole omnidirectional antennas. The street canyon is approximately 130 m in length and 15 m in width, surrounded by buildings ranging from 20 m to 44 m height. The ground Rx antenna is placed at a height of 2 m.

空对地（Air-to-ground, A2G）信道在无人机与地面终端的可靠通信中发挥着关键作用。A2G信道建模是当前的研究热点，但实际场景下用于模型验证与对比的实测数据却较为匮乏。
本团队在城市场景下开展了3.6 GHz频段、带宽61.44 MHz的信道测量实验。发射端（Transmitter, Tx）与接收端（Receiver, Rx）均采用偶极子全向天线。本次测量的街道峡谷长约130米、宽15米，周边建筑高度介于20米至44米之间，地面接收天线的架设高度为2米。
