Abstract
In a method for the precise angle determination of targets by means of a multiple unit antenna radar system, individual antenna patterns are generated in separate directions by at least three feeds (F−,, F,, F,) which are spatially offset with respect to one another and which illuminate a joint collimator (R). By simultaneous and phase-correct excitation of several of the feeds, at least two combination antenna diagrams are generated, by means of which the angle determination takes place. The intersecting points of the combination antenna diagrams, are situated in angle ranges in which the exact angle determination is desired.
