高光谱干涉探测仪是一种利用干涉原理来测量输入辐射的光谱强度和光谱分布的仪器,它的用途十分广泛。可用于军事伪装目标的多光谱识别、农作物生长状况检测以及航空航天大气温湿廓线的遥感等等。对高光谱大气探测仪输出的干涉信号形式进行了分析,根据其特点,详细讨论了前放的噪声匹配的问题,控制噪声在探测器噪声的背景限下.然后用滤波等方法进一步减少噪声,进行采样后获取有用信息。结合信号特征设计了整个数据采集电路。
Hyperspectral interferometry is an instrument that uses the principle of interference to measure the spectral intensity and spectral distribution of incoming radiation and is used in a wide variety of applications. It can be used for multi-spectral identification of military camouflage targets, detection of crop growth status, remote sensing of temperature and humidity profile of aerospace atmosphere, and the like. According to its characteristics, the problem of noise matching in pre-release is discussed in detail, and the control noise is limited in the background of the detector noise.Furthermore, the noise is further reduced by filtering and other methods, After sampling to obtain useful information. Combined with the signal characteristics of the design of the entire data acquisition circuit.
