红外系统包括所有用于探测和处理红外能源的信号信息的装置。红外能源这一术语的意义是广泛的,它包括:(1)由于辐射或物体自身发射所造成的能源,(2)与周围环境相比,其能量较小的能源,称为负能源或对比度能源,(3)对另一个物体的能量反射所形成的实际能源,诸如被太阳光照明或被红外灯光照明的物体的反射。探测系统的最终目的,是要起到收集辐射计数据,确定物体的存在及位置,和对制导系统提供控制信号的功能。在这个意义上,探测系统就是一个大系统中的分系统。红外系统的基本功能是为大系统提供一个输入量,并且一般说来,还应敏感和处理信息,成为适用于进行判断的形式。
The infrared system includes all the means for detecting and processing the signal information of the infrared energy source. The term infrared energy has a wide range of meanings, including: (1) Energy resulting from radiation or the emission of an object by itself, (2) Energy with less energy than the surrounding environment, called negative energy or contrast Energy, and (3) the actual energy created by the energy reflections of another object, such as the reflection of objects that are illuminated by sunlight or by infrared light. The ultimate goal of a detection system is to gather radiometer data, determine the presence and location of objects, and provide control signals to the guidance system. In this sense, the detection system is a subsystem of a large system. The basic function of an infrared system is to provide an input to a large system, and in general, it should also be sensitive and process information as a form suitable for making judgments.
