Abstract: Due to space and system power limitation of fuze, when laser proximity fuze is used in conventional ammunition, multiple lasers and multiple laser receivers can't be laid out. Meanwhile, system architecture is required to be as simple as possible. Therefore, the traditional layout of the beam can't be directly applied. A new rotation circumferential scanning program of large field of single-beam, was designed. Missile target encounter model was established and theoretical analysis on target acquisition rate was conducted. System error factors were discussed. The initial prototype was processed and high-speed wind tunnel experiment was done. The results show that the program can achieve reliable connection when the speed is less then 80 000 r/min, 360 large field of detection of laser proximity fuze used in conventional ammunition can be realized. Under the premise of ensuring target acquisition rate, fuze space utilization of conventional munitions and system power can be effectively reduced.
