Paper Abstract

Among passive methods for a cloud base height (CBH) detection, bistatic and monostatic methods are known. In the first case a triangulation method with two photodetectors is used. A drawback of this method is a need in obtaining images of the one overcast fragment by two spatially separated cameras in the course of shot time. In consequence, images have different view angles and the problem of identification of this fragment appears. The passive monostatic method for CBH detection does not have these demerits. For measurement by this method, linear sizes of object should be known. But for a case of CBH detection it is impossible, because cloudiness can change in the course of short time. The offered method does not demand knowledge about linear sizes of cloudiness fragments. The method uses dependence of scale change of object image at change of focal length of camera lens depending on distance up to object.
