一种红外导引头注入式试验中目标场景复杂度的评估方法

Target Scene Complexity Metrics Based on Digital Image Injection Test for IR Imaging Seeker

针对红外导引头注入式试验过程,研究分析影响红外制导结果的主要场景因素,定义面向制导过程的目标场景复杂度的概念;根据红外导引头在不同目标场景中制导难点的差异,将目标场景根据目标的运动状态分为“静态目标场景”、“动态目标场景”两种类型,分别建立两种情况下目标场景复杂度的计算表述方法,并通过仿真实验验证评估方法的可行性。研究结果对红外制导仿真试验前期注入目标场景的构建和选择提供了数据理论参考,同时能作为红外制导武器场景适应能力评价工作的数据依托。

The process of digital image injection test for IR imaging seeker was analyzed,and the main factors of scenes affecting the results of the guidance experiments were investigated.The target scene complexity metrics in the digital image injection test for the IR imaging seeker were defined according to the guidance difficulties for the IR seeker in different target scenes.The target scenes were divided into“static target scene”and“dynamic target scene.”Two target scene complexity metrics were set up for different types of scenes.Our results can provide data support for the construction of scenes before digital image injection tests.They can also be used proof data to evaluate the effectiveness of the guidance of IR imaging seeker.
