A method for adaptive target processing in a vehicle the radar involves first detecting targets in the monitored environment with respect to their speed and location in a standard mode of the radar sensor, and then switching to a precision mode, in which the distance measuring range of the radar sensor is adapted to the target surroundings detected in the standard mode. More particularly, the measuring accuracy and/or resolution regarding speed is increased by increasing the time of observation within the distance measuring range adapted to the target surroundings.

Method for adaptive target processing in a motor vehicle radar system

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&minus;,, 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.
