Abstract

With the development of semiconductor laser technology, laser proximity fuzes have been widely used in various kinds of guided missiles and routine ammunitions. Combined with the current situation, the digital laser fuzes system based on the FPGA has been proposed in this paper. Combined with the current situation, the system has been divided into emitting module, receiving module and signal processing module, the three modules have been analyzed in details. In the emitting module, the driven circuit based on the FPGA has been developed, the laser pulse with 20ns width and 10kHz repetition frequency have been obtained. Meanwhile, the emitting optical system and receiving optical system have been designed. In the receiving module, the receiving circuit with preamplifier and A/D sampling and convert circuit have been developed. In the signal processing module, anti-interference methods were proposed which can find applications in the laser proximity fuze research.
