Abstract

A method for determining the visual range improves the visual range measurement adopted as a basis, to the end that the measurement of the visual range can take place using one emitter and using one receiver, which are disposed to be stationary. The method permits the determination of the visual range, even though an obstacle is situated within the field of view. A comparison of a measured backscatter signal with a specimen curve permits the determination of the visual range from the intensity curve obtained, without any need, for this purpose, of further information such as, for example, the direction from which the backscatter signal comes.
