Paper Abstract

A criterion of spatial-angular efficiency (SAE) of remote electro-optical systems for atmosphere monitoring is formulated. The dependencies of the SAE from normalized range and minimal operating range for different optical receiving schemes of ground-based biaxial LIDAR are analyzed. It is shown that low SAE of traditional VIS & NIR systems is a main cause of a low signal-to-background-noise ratio at the photodetector input, the considerably measurements errors, and the following low accuracy of atmospheric optical parameters reconstruction. The most effective protection against sky background radiation in such systems consists in forming an angular field according to the introduced SAE criterion. Some approaches to achieve high value of the SAE-parameter for receiving system optimization are discussed.
