Abstract
A method for measuring the distance and speed of objects using electromagnetic waves with a motor vehicle radar system is described, electromagnetic waves being transmitted and simultaneously received, the transmitted electromagnetic waves being modulated in the shape of a ramp, at least the signals received during one rise and one drop of the frequency of the transmitted signal being mixed in each case with the transmitted signal, a number of intermediate frequency signals being formed, and the distance and speed of the object being calculated using the intermediate frequency, a weather condition in the vicinity of the motor vehicle and/or a disturbance in the motor vehicle radar system being identified on the basis of characteristic intermediate frequency signals.
