Abstract

Humanity can struggle with the dangerous cosmic objects in our time and its parameters knowledges are needed. A present paper deals with prospects for the cosmic IR lasers using for remote sensing measurement of the various cosmic objects parameters: dimensions are more then 100 m, velocity is more then 30 km/s. A laser under solar energy pumping was elaborated. The more effective laser parameters were defined for the smaller bodies velocity analysis. The laser is supplied with an automatic tuning optical system. Possibilities are estimated for diagnostic measurements with using modulated laser radiation. The C02 or solid states lidars are needed for the asteroids detection’s at a distances of 30 000 km to 10 Mkm from an earth surface. A laser Doppler anemometer method with adaptive selection is used. The peak transmitted optical power depends on photoreceiver parameters and other system components. The high sensitivity ( 500 V/W ) photoreceivers without a cooling are elaborated today. A constant lasers exit power is upper 100 kW, at present. Therefore, a such diagnostic task can be solved by the measuring system with a high power laser and the new photoreceivers.
