为了评估激光对红外制导武器的干扰效果,需要研制一种中波红外跟踪处理系统来辅助进行干扰效果研究,在系统设计之初,往往需要对其进行理论分析。通过对目标特性进行分析处理后,分别从视场及焦距、NETD、MRTD、最大保精度跟踪角速度和角加速度等几个系统关键性能参数的确定进行了详细的分析论证,为系统的实现奠定了理论基础。 In order to evaluate the effect of laser on the infrared guidance weapon, we need to develop a mid-wave infrared tracking system to assist in the study of the interference effect. At the beginning of the system design, it is often necessary to conduct theoretical analysis. After the analysis and processing of the target characteristics, the key performance parameters of several systems such as the field of view and focal length, NETD, MRTD, maximum preserving accuracy tracking angular velocity and angular acceleration were analyzed and proved respectively, which laid the foundation for the realization of the system Theoretical basis.
