ABSTRACT:
A method for measuring cloud height, in which a train of light pulses is sent from a transmitter into the investigated air space. From each of a number of different height intervals, signals reflected towards a receiver are integrated and measured. The time, the pulse number, the pulse frequency and/or the pulse energy for each height interval are controlled with respect to the energy reflected and received in the receiver from underlying measuring intervals, thus obtaining compensation for losses in the energy of the light pulses in reaching the respective level.
