一、引言噪声是探测器的基本参量之一。噪声的测量一直受到充分的重视。有关各种类型探测器的噪声谱及其理论分析已广泛见诸于文献报导。众所周知,噪声谱的研究对了解探测器的噪声机理和红外探测器的工艺水平具有重大的实际意义。但当考虑实际应用尤其是自动导引、高空照相、搜索和跟踪等应用时,仅仅作以上的研究就不够充分。在进行噪声频谱测量时,探测器一般处于静止状态。但当实际应用时,由于整机的运动探测器具有一定的速度和加速
First, the introduction of noise is one of the basic parameters of the detector. The measurement of noise has been given full consideration. The noise spectrum of various types of detectors and their theoretical analysis have been widely reported in the literature. It is well known that the study of noise spectrum is of great practical significance for understanding the noise mechanism of the detector and the technological level of the infrared detector. However, when considering practical applications, especially for automatic guidance, aerial photography, search and tracking applications, the above research alone is not sufficient. In the noise spectrum measurement, the detector is generally at rest. However, when the practical application, due to the machine’s motion detector has a certain speed and acceleration
