Method for precisely measuring target direction using a radar system having multiple beams

摘要

The invention relates to a method for the accurate angle determination of targets by means of a multi-antenna radar system, with the individual antenna devices (A1, A0, A1) by at least three spatially mutually offset feed (F1, F0, F1) having a common collimator (R) light, are generated by simultaneous and phase-correct control of a plurality of feeds (F1, F0, F0, F1) at least two combination antenna patterns (A0 / -1, A0 / 1) are generated based on which the angular determination is carried out, wherein the intersections of the combination antenna patterns generated come to lie in angular ranges in which the exact angle determination is to take place.
