Abstract :
Equipment for active location with optical and radar wave bands receives information on the object from the formation of sounding signals and the analysis of scattered signal. Radar systems are successfully used in monitoring environment, remote sensing of polarization characteristics, measurement of hydrometeor characteristics. Laser locators (lidars), on the basis of polarization measurements, allow one to estimate the characteristics of atmospheric aerosols, to control for atmospheric pollution. The high frequency of laser radiation provides very narrow diagrams of lidar direction, the formation of impulse sounding signals of short duration and the following peculiarities: great time of the operating region review; strong weakening by atmosphere of the sounding laser radiations and those reflected from the target; most of the targets are spacially distributed. Superposition of radar and optical channels in a complex location system (CLS) allows one to avoid the limitation of each of the systems. The paper describes the concurrent polarization operation mode of a CLS system
