Measured A2G Channel Dataset (CIR) in Multiple Scenarios
Description
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. This dataset provides A2G channel CIR under multiple scenarios at the 3.6 GHz band with a bandwidth of 61.44 MHz. Instrucitons can also be found in the guidemanual.pdf. More details about the channel sounder and dataset can be found in the following references. [1].

Files
Steps to reproduce
All measured data are stored within a primary directory, which contains three subdirectories corresponding to the three measurement scenarios: sports field, farmland, and over-water. Each subdirectory includes two data files, representing the channel data acquired at two different UAV flight altitudes in each scenario. Each file includes three types of parameters: 1) system parameters, i.e., carrier frequency and sample rate; 2) GPS data such as the longitude, latitude, altitude, and timestamp of the transmitter (TX) and the ground receiver (RX); 3) measured CIR data. For example, in the sports field scenario at a UAV flight altitude of 10 m, the measured A2G CIR data are stored in an .xls file. The first row contains the column headers, while the second row provides the GPS location information of the RX. Starting from the third row, the measured CIR values are presented, with an effective data dimension of 110 × 200. Taking the third row as an example, the first column corresponds to the GPS longitude, the second to latitude, and the third to altitude, expressed in meters. The fourth to sixth columns contain the timestamp (in seconds), carrier frequency, and sampling rate, respectively. Columns 7 through 206 contain the measured CIR data corresponding to the GPS locations.
