红外搜索系统的作用距离及其等效检验

Active Distance and Its Equivalent Test for Infrared Search System

推导了红外搜索系统的作用距离方程,并修正传统的红外搜索系统作用距离方程。在检测条件偏离系统设计所规定的大气条件和目标特性情况下,推导出不同目标、不同大气条件下作用距离等效折算公式,用模拟目标代替规定目标进行检验。所述方法可应用于系统设计和检验,以及评价红外搜索系统的综合性能。

An active distance equation of infrared search system has been derived. The traditional active distance equation of infrared search system is corrected. If the test conditions are deviated from the regular atmosphere condition and objective radiation properties for the system design, it is necessary to derive equivalent converting formula of active distances for different target properties and atmosphere condition, the simulating target is used for testing instead of prescriptive target. The equation and method can be used to design and test system, and to evaluate comprehensive performances for the infrared search system.
