摘　　要：蓝绿激光在水下目标非声探测中具有广泛的应用前景,但现有的探测模型尚未考虑探测概率与自导系统的匹配问题。为了获得最佳探测效果,建立基于脱靶量的水下目标激光周视扫描探测模型。仿真结果表明:随脱靶量增加,在相同发射频率下,增大光束发射倾角能显著提高探测概率,但减少了后级系统的处理时间;此外,随脱靶量增加,为避免探测漏检,应提高发射频率,减小光束发射步进角度。最后,通过仿真分析给出不同脱靶量下探测系统关键参数的最优设计。文中所建模型对探测系统、自导系统的匹配设计提供了一定的理论参考。Blue-green laser has broad application prospects in non-acoustic detection of underwater targets. However, the existing detection models have not considered the problem of matching the detection probability with the self-guided system. A target detection model of underwater laser scanning detecting system was established based on undershoot distance to match the guiding precision. The simulation results shows that an increasing undershoot distance needs an increasing emit angle to get high detection probability at a certain emit frequency, which however leads to a decreasing acting time for the following system. In addition, an increasing undershoot distance needs an increasing emit frequency and a decreasing step angle to avoid missing the target. Finally, the simulation provides an optimal range for undershoot distance and system parameter. The model and the simulation results provide theoretic basis for the matching up design of guiding system and detecting system.
