AB  - This dataset is obtained from Cuiying Mountain in Yuzhong County, Lanzhou City, Gansu Province, using a FlyCart 30 drone equipped with a wideband special coil transient electromagnetic system. The experimental center is located at longitude 104.13521 ° and latitude 35.94206 °. During the data production process, three sets of measured data were obtained, including hover tests, small-scale flight tests, and large-scale flight tests. The original data is the time-domain voltage sequence of transient electromagnetic waves in unmanned aerial vehicle (UAV) aviation. Most of the data covers effective attenuation signals within 3-17 milliseconds in time range, and the spatial range varies with the UAV trajectory distribution. The dataset includes emission parameters, measurement line numbers, measurement point coordinates and elevations, and corresponding temporal electromagnetic responses, with meter level spatial positioning accuracy and microsecond level time data sampling rate. The characteristic of this data is the use of a self-developed system with high magnetic moment (≥ 400 ampere square meters) and lightweight (≤ 10 kilograms). As the measured electromagnetic data obtained for the loess slope environment, this dataset has good consistency between profiles and can provide reliable reference for loess structure detection and related algorithm verification.
