Abstract: An evaluation method for radar measurement data of a mobile radar measurement system includes the steps of preparing a multidimensional range-Doppler map from the radar measurement data. In this evaluation method, each multidimensional range-Doppler map is stored together with time information. Moreover, at least one multidimensional range-Doppler map with time information is propagated on the basis of known movement data of the radar measurement system to the current time. The multiple multidimensional range-Doppler maps may be combined to form a combined range-Doppler map.
