Abstract :
A dual channel microwave Doppler-sensor-module for 24 GHz is presented. The microwave components like oscillator, mixer, antenna and their characteristics in the integrated MIC are discussed. The influence of the antenna pattern and the road surface is considered. A simulation of the system shows their influence on the Doppler spectra and the data evaluation
