The detection method based on UAV has attracted more and more scholars’ attention. In this paper, the basic principle of gradient tensor is discussed firstly, and then the composition of gradient tensor system and the structure are described. After the length of baseline is determined by simulation, a signal collector based on ARM CortexM3 is designed. Through the collector, 12 channels of signals can be collected synchronously, and RTK time and position information are integrated into each frame. The information after framing is transmitted to the ground station for further processing.
