Abstract:	The wireless setting technology is the basis of realizing the precise control of a projectile burst point. Aiming at the low level of intelligence and informatization of small caliber projectiles at present, a wireless muzzle setting system based on DPSK modulation is designed to quickly set the factors affecting the trajectory into the electronic fuze of small caliber projectiles. The information acquisition module converts the collected environment information and the input transmission information into binary data and transmits them to FPGA. Then, FPGA performs DPSK modulation to the binary data. The modulated signal is amplified by the current, and then the electrical signal is converted into the magnetic field signal through the transmission coil. To achieve maximum power transmission, the coil parameters are designed. The non coherent demodulation of the internal receiver of the fuze is realized through AD acquisition, which reduces the volume. A light gas gun experiment is carried out to verify the system. The results show that the system can realize the wireless muzzle setting of small caliber projectiles.
