Abstract
A dual channel microwave Doppler-Sensor-Module for 24 GHz is presented . This front end is well-suited for true ground speed and distance mea surements in all kinds of automotive applications. The microwave compo nents such as oscillator, mixer, antenna and their characteristics in the MIC are discussed. The influence of the antenna pattern and the ro ad surface on the Doppler spectrum is treated in a D-3-field theoretic al simulation. This simulation takes the antenna nearfield and the dis tributed scattering of the road into account.
