摘要

Influence of high-repetition-rate noise on a range-gated laser ranging and tracking system (LRTS) is studied both theoretically and experimentally. The interference mechanism of high-repetition-rate noise on range gates is revealed. The interference effect, especially the effect caused by relative shift between signal and noise, is presented through theoretical analysis and numerical simulation. In order to verify the simulation model, both electrical closed circuit and optical circuit experiments are further conducted. Both the simulation model and experiment results show that both periodic and nonperiodic noise pulses can enter the range gates of a LRTS and affect its operation with both their high repetition rate and relative shift to echo pulses.
