基于偏最小二乘的红外探测设备指标评估方法

摘要

针对长期以来靶场鉴定试验中红外探测跟踪设备主要性能指标难以评估的问题,提出了一种利用非典型环境条件下的小样本试验数据进行指标参数评估的方法.通过对偏最小二乘回归方法的分析,结合红外探测跟踪设备的战术指标和工作特点,建立了红外探测跟踪设备偏最小二乘回归单指标评估模型,并通过实例分析表明了方法的有效性和正确性.%To evaluate the tactical indexes of infrared detector during range evaluation test, a method of evaluating tactical indexes utilizing small samples test data is presented in untypical circumstance. The single index evaluation model is established based on the analysis of the PLSR method and the research of characteristics and tactical indexes of infrared detector. Example shows that this method is effective and accurate.
