Abstract

With the development of semiconductor laser technology, laser proximity fuzes have been widely used in various kinds of guided missiles and routine ammunitions. And its precision of ranging has a direct influence on the overall performance of the system. This work employed Spartan III series FPGA chip from Xilinx company. Through phase shifting the primary reference clock and ranging with four doubled-frequency clocks with each phase shiftings of 90 degree, the ranging precision can be improved obviously. The theoretical ranging error is 0.1875m and the result has been proven by simulation with Modelsim. Valuable conclusions were drawn for improving the ranging precision of laser fuze.
