摘要

The method of remote detection (MRD) of zones of increased concentration ("clouds") of impurity gases and vapors in the air is based on absorption by these gases of ultra-violet (UV) radiation or infra-red (IR) radiation of the scene (topographical targets, i.e. any objects in the field of vision of the device including the Earth surface, the sky, etc.). The method is recording of the images of the scene in very narrow spectral ranges coinciding witch spectral bands of absorption of these impurities. MRD can be realized with the help of two types of devices: 1. Devices on the basis of thermal imagers, recording impurity absorption on vibrationel- rotationel transitions in the infrared (IR) spectral region. 2. Devices on the basis of electron-optical image intensifiers (Ⅱ) recording impurity absorption on electron - vibrationel transitions in the ultra-violet (UV) spectral region. In the report the calculations of utmost sensitivity capabilities MRD with reference to each of devices, implementing it are carried.
