Abstract
A radar method and a device for carrying out the method include estimating an azimuth angle of each target object from determined variables of distance or range, relative speed and relative acceleration after Kalman filtering and separating out target objects having a physically impossible behavior (tracking and prediction). That is used to determine which target objects are located on a roadway occupied by a vehicle and which are the most dangerous thereof. Indication, warning or action thresholds are determined as a function of driving behavior of the driver, road conditions and weather conditions. Indication, warning or action signals (in the brakes, throttle valve or gear shift of the vehicle) result if the thresholds are exceeded or undershot by the range, the relative speed and the relative acceleration.
