Abstract:	In view of the fact that the distance between the current non traversing coil and the receiving coil is too long, it is difficult for the fuze to pick up the set signal in the ionization noise of the muzzle. In addition, the received signal will have the problem of signal inversion at the muzzle, causing the receive window to be split. Finally, the high speed movement of the fuze makes the amplitude of the sensed signal vary greatly. Aiming at these problems, this paper first establishes the induction setting theory and simulates the movement path of the coil, and analyzes the magnetic field inhomogeneity in the induction window and the unequal envelope amplitude of the signal waveform. By using the new method to adjust the angle parameters, the changes of the system transmission performance and the setting window are adjusted to increase the uniformity change law. The theoretical simulation and experimental results show that, as the adjustment coil angle increases, the transmission performance of the system decreases, and the setting window decreases significantly but the uniformity increases. For a system where the transmitting coil and the receiving coil transmit the same amount, when the angle radius (α/2) adjusted by the transmitting coil is equal to the distance between the receiving coil and the center of the transmitting coil (z), the setting window is the largest and the relative uniformity change is small.
