Abstract
A method for operating a radar, having the following steps: determining first and second differential signals from a first and second transmitted frequency-modulated signal and received components of the first and second transmitted frequency-modulated signal reflected by a plurality of objects; determining in each case one first and one second chirp signal for each first and the second differential signal, the first chirp signal corresponding to the double differentiation of the phase of the first and the second differential signal with respect to time; assigning one of the first differential signals to one of the second differential signals, based on a correspondence of the first chirp signal, that is assigned to the one first differential signal, to the second chirp signal that is assigned to the one second differential signal; and determining the separation distance and/or the relative speed of one of the objects, based on the one first differential signal and the one second differential signal assigned to the first differential signal.
