基于p_∞模型的目标搜索仿真研究

Research on the Simulation of Target Searching Based on p_∞ Model

该文分析了经典搜索模型中存在的局限性,详细介绍了美军NVESD(N ight V ision and E lectron ic Sensors D irectorate)开发的p∞搜索模型。p∞模型可反映可见光观察仪及热成像仪的观瞄性能,并可用于不同观察仪器搜索能力的比较,同时该模型还能够反映大气状况、目标背景等战场环境因素对观察仪器搜索能力的影响。该文利用该模型对坦克作战活动的目标搜索行为进行了仿真研究。试验表明,该模型能够较真实地反映对装甲目标的搜索过程。

The limitation of the classical models of target searching is analyzed and the p∞ model is put forward which is developed by NVESD（ Night Vision and Electronic Sensors Directorate of USA army）. The p∞ model could be used to analyze the searching performance of optical and infrared observers and to compare the performance between different observers in simulation. Meanwhile, the factors such as atmospheric condition and the background of target which could affect the performance of observers are included in the model. The action of target searching of tank is simulated based on the model in this thesis. It proves that the model could demonstrate the searching process with high fidelity.
