摘　　要：为了全面、科学、合理地评价夜视系统的性能指标和作战效能,避免在野外实测微光夜视仪的过程中投入大量的人力、物力和财力,在微光成像夜视系统阈值探测理论和视景仿真技术的基础上,开发了一个集计算和仿真功能于一体的应用软件,提出了采用三维视景仿真软件作为夜视系统性能评估工具的新方法。该软件可以实现对微光夜视系统夜间成像的仿真和视距的评估。以三代微光夜视观瞄系统为试验对象,对其在不同夜间环境下进行了性能评估和野外测试。通过对结果的分析和比较,证实了该评估方法是实用的。In order to properly evaluate the performance and efficacy of night vision systems and save the test resource,a new method, in which a software of VC++-Creator-Vega is taken as a tool for performance evaluation of LLL night vision system,is put forward based on the threshold detection theory and the scene simulation technology of LLL night vision systems.The experiments on a LLL night vision system with Gen III intensifier were carried out under the specific circumstances.The viewing distance was estimated and simulated by the software.The comparison between theoretical data and the experimental data was made.The result proves that the performance evaluation software is effective and the system design is feasible.
