Abstract
A system and a method are provided. The system includes an airborne detection system and a ground assistance system. The airborne detection system includes an unmanned aerial vehicle, a receiving device, a transmitting device, and a connecting device. The transmitting device includes a transmitting sub-device, a transmitting coil, and a bucking coil. The receiving device includes a receiving sub-device and a three-component magnetic sensor. The connecting device includes a signal and rope composite cable and is used to connect the UAV, the transmitting device, and the receiving device. The three-component magnetic sensor is used to acquire three-component electromagnetic data. The bucking coil is disposed on an inner side of the transmitting coil, and coil winding direction of the transmitting coil and the bucking coil causes current directions flowing through the transmitting coil and the bucking coil to be opposite to each other, to reduce an electromagnetic interference.
