Cars with electronically controlled all wheel drive, antiblocking systems or anti slip control need speed sensors, measuring True Speed Over Ground (TSOG). By comparing wheel speed and TSOG-value, informations about blocking or slipping rates are obtained. In this paper a Doppler radar sensor for TSOG-measurements is presented, based on millimeter-wave frontends and digital processing of baseband signals. For the estimation of the doppler frequency an FFT-based method extended by sensor model based algorithms for postprocessing is used. Measurement results will be given showing excellent system performance even under adverse environmental conditions.
