This application belongs to the field of geophysical exploration technology, specifically disclosing a differential transient electromagnetic method device and its unexploded ordnance detection method. In the differential transient electromagnetic method device, the transmitter injects a transmission current into the transmission loop, generating a primary field excitation signal. Under the influence of the primary field excitation signal, the subsurface anomaly target generates a secondary field excitation signal. The receiving coil assembly, based on a differential coil structure, synchronously cancels the primary field excitation signal and the uniform background signal in the induced voltage, amplifying the local asymmetric differential signal generated by the subsurface anomaly target. The receiver performs time-series analysis on the local asymmetric differential signal, extracts differential signal features, and achieves the location and identification of the subsurface anomaly target. This application is suitable for the detection of shallowly buried small bodies such as UXOs. The overall deployment range of the device is small, facilitating rapid deployment and mobile observation in the field.
