摘　　要：单台光电设备覆盖空域小、探测盲区大,对超低空飞行、隐身性强的目标探测概率低,光电组网能够扩展空域覆盖范围,提高目标探测概率。为获取最优光电组网方案,对其探测概率进行评估。给出基于目标运动模型的目标截获与数据获取仿真方法,采用基于最小一乘估计的自适应加权融合算法对目标数据融合处理。在单站目标探测概率基础上,建立多站目标探测概率的计算模型以及基于多站重叠覆盖区域的系统探测概率计算模型,提出光电组网系统对目标的探测概率评估方法。结合星型布站实例,对光电组网探测概率量化评估。评估结果表明:若单站探测概率≥80%,则组网探测概率≥89.4%;组网探测概率仿真评估能够为光电组网方案提供数据参考,支撑构建网络化光电探测系统。Single electro-optical device covers a small airspace and has a large detection blind area.It has a low detection probability for targets with strong invisibility and low altitude flight.Electro-optical networking can expand the coverage of airspace and improve the detection probability of targets.In order to obtain the optimal electro-optical networking scheme,its detection probability needs to be evaluated.A simulation method for target interception and data acquisition based on target motion model is given,and an adaptive weighted fusion algorithm based on least-squares estimation is used to process target data fusion.On the basis of single-station target detection probability,the calculation model of multi-station target detection probability and the calculation model of system detection probability based on overlapping coverage area of multi-station are established,and the evaluation method for target detection probability of networked electro-optical system is presented.The detection probability ofelectro-optical group network is quantitatively evaluated by taking the star distribution for an example.If the detection probability of single station is more than 80%,the detection probability of group network is more than 89.4%.The simulation and evaluation of detection probability of networking can provide data reference for electro-opticalnetworking scheme and support the construction of networked electro-optical detection system.
