ABSTRACT:
A method for the laser-optical measurement of cooperative objects at an urtain distance by emission of a laser beam and evaluation of the echo reflected at the object, more especially for simulation of firing for practice purposes. In order to be able to adapt the size of the beam cross-section to the target conditions within limited distance ranges, within a coherent measurement process a plurality of similar individual measurements are undertaken with differing beam divergences, which are associated in each instance with differing distance ranges. If echos which come from a distance substantially greater than the distance associated with the set divergence are received, then these are excluded from the evaluation.
