摘　　要：目标的红外辐射特性是实现目标隐身性能评估与目标识别的重要红外数据之一。传统的红外辐射反演技术会将目标分为点目标和面目标来分别加以处理。考虑到靶场目标的飞行姿态和距离变化的影响,利用现有的红外辐射特性数据难以明确地将点目标与面目标分开处理。就此提出了一种通用的红外辐射特性测量方法。该方法可统一实现目标特性的处理,并简化了数据处理的模式。采用口径为600 mm的中波红外辐射特性测量系统对目标反演精度进行了验证。在积分时间为2000μs和3000μs的条件下分别对目标进行了数据处理,证实了本文方法的有效性。结果表明,该方法具有一定的工程应用意义。The infrared radiation characteristic of the target is one of the important infrared data for stealth performance evaluation and target recognition.The traditional infrared radiation inversion technology categorizes the targets into point targets and surface targets for processing respectively.Considering the influence of the flight attitude and range variation of the target,it is difficult to categorize the targets into point targets and surface targets by using the present infrared radiation characteristic data.A general method for measuring infrared radiation characteristics is proposed in this paper,which can unify the processing of target characteristics and simplify the data processing mode.In this paper,the accuracy of target inversion is verified by using this method based on the measuring system of medium wave infrared radiation characteristics of 600 mm caliber.The target data is processed respectively under the conditions of 2000μs and 3000μs integration time,which proves the effectiveness of the proposed algorithm.This method has certain engineering application significance.
