摘要: 为全面评价激光定距引信的探测能力，确定其随距离变化的规律，通过推导脉冲激光测距回波方程，建立脉冲激光测距数据分布解析方程并提出误差量化评价方法。仿真分析并评估了探测距离对回波信号及探测能力各指标的影响，最后通过试验得到验证。结果表明：可靠测程内，引信可实现可靠探测，随探测距离减小，测距随机误差先减小后增加，系统误差逐渐增加；引信最大可靠测程为84.8 m，测程内随机误差为0.22~0.73 m，满足引信远程定距的需求；提高阈值可明显改善测距误差，但会造成可靠测程减小。所得探测能力变化规律与评价方法可为脉冲激光引信设计与应用提供理论依据。

Abstract: To comprehensively evaluate the detection capability of the laser fixed-distance fuze, and obtain the variation in detection capability with the detection distance, the analytic equation of the distribution of pulsed laser ranging was established by deriving the echo equation of pulsed laser ranging, and an error quantification evaluation method was also proposed. The influence of detection distance on echo signal and the indicators of detection capability were analyzed and evaluated, and the results were verified by experiments. Results indicate that the detection of fuze is reliable within its reliable range. In addition, the random ranging error tends to initially decreases and then increases while the system error has the trend to increase gradually as the detection distance decrease. The maximum reliable range of fuze is 84.8 m and the random error is 0.22-0.73 m in the reliable range, thus satisfying the requirement of remote fixed-distance fuze. Besides, with the increase of the threshold, the range error can be obviously improved a lot, although the reliable range is caused to be reduced. The variation rules and evaluation methods in this work can provide a theoretical basis for the design and application of the pulsed laser fuze.
