Automotive radar sensors are applied to measure the target range, azimuth angle and radial velocity simultaneously even in multiple target situations. The precisely measured radar data for each single target are necessary for target tracking in all different advanced driver assistance systems (ADAS) applied e.g. in highway scenarios. But in typical city traffic situations the radar measurement needs even additionally some information about the lateral velocity component of each detected target and vehicle. It is shown in this paper that the lateral velocity of an extended target can indeed be measured even by a single radar measurement. For an automotive radar sensor a high spectral resolution is required in this case with a sufficiently long time on target. In this paper a lateral velocity (cross-range) measurement procedure is presented. The basis for this technique is a measurement of radial velocity and azimuth angle for each reflection point of a single radar object. Radial velocity is measured by classical Doppler-frequency analysis and azimuth angle has been measured by monopulse technique. All standard automotive radar sensors in the 24 GHz domain with this discussed measurement capability are of high importance for automotive driver assistance systems. These results are shown on an analytical and experimental basis.
