ABSTRACT:
A method for orienting a radar installation which possesses an at least approximatingly axial-symmetrical antenna radiation or beam characteristic towards a target. The radar beam which is emitted by the radar installation is reflected or scattered back at the target and the backscattered radar beam is evaluated or plotted in a measurement evaluating device of the radar installation for purposes of determining or identifying the target. Employed is a target with three target elements which are arranged in the corners of an at least approximately equilateral triangle, the centerpoint of which corresponds to the desired target point, in which there is effected a separating of the three radar signals which are reflected or scattered back by the three target elements, and that from the values of the amplitudes of the three backscattered radar signals, through the utilization of the measurement evaluating circuit, there is determined the position of the target point which is located between the target elements.
