- Abstract:
- Undersatellite systems of remote sounding (USRS) of the terrestrial plants are enough effective for the solution of many important problems. Research of the natural resources, monitoring of the environment's state, observation of state of the agriculture and water facilities, also the natural cataclysms development dynamics observation problems, etc. are among them. The remote sounding for the military and prospecting purposes is very important as well. In turn, USRS, equipped by board special gears and computer facilities, are realized on the basis of aircraft, including the small-sized and cost-effective pilotless aircraft (planes, helicopters). The conditions of measurement, conversion and processing of the signals in USRS demand higher and rigid technical and metrology indexes of the board devices. Multi-channel spectrometers of the various types are one of the board devices, carried out the measurement in visible range and near infrared range of electromagnetic radiation's spectrum. The output signals of these spectrometric devices are formed after preprocessing the radiation signals, coming from the researched terrestrial plant, the measurement standard and the sky accordingly, on the board. Therefore the measurements with help of the spectrometric devices are fulfilled in the following four different regimes: "terrestrial plant", "sky", "standard" and "darkness current", which are usually installed with help of the special optical-electromechanical blocks (modulators), characterized by lag effect, hardness of construction and setup, high consumption of electric energy and insufficient reliability. All showed above raise mass-size indexes of the spectrometric devices, hardware expenditures, diminish speed and reliability.
