Abstract

A 24 GHz high-performance Doppler sensor for non-contact measurement of vehicle speed and position is reported. The compact dimensions and the economical design make the sensor ideally suited for automotive applications. A special feature is the 24 GHz fundamental-frequency dielectric resonator oscillator employing a low-cost packaged HEMT. An excellent phase-noise behavior and good temperature stability are achieved due to higher-order mode operation of the dielectric resonator. The new Doppler sensor provides high reliability and gives excellent measurement results in both car and train tests.
