Abstract: A reference noise cancellation device for a transient electromagnetic field is provided. The device includes a transmitter, a transmitting loop, a reference coil, a signal coil and a receiver. The transmitter generates a measurement timing sequence to trigger the receiver to synchronously record the induction signal in the signal coil and the electromagnetic noise in the reference coil. A bipolar current waveform is generated and is injected into the transmitting loop through the first connecting line. The signal coil receives an induced magnetic field of an underground conductor and surrounding magnetic field noise. The reference coil receives surrounding electromagnetic noise. The receiver receives and records the induced magnetic field and surrounding electromagnetic noise of the underground conductor in the signal coil and the surrounding electromagnetic noise in the reference coil.
