ABSTRACT:
A Doppler radar module constructed using micro-stripline technology is used in motion sensors and includes a local oscillator stabilized with a dielectric resonator that feeds a microwave antenna via a mixer that is connected in series. The transmission signal is emitted from the microwave antenna and is reflected back from an object where it is received by the antenna and forwarded to the mixer. The mixer mixes the reflected signal with a portion of the oscillator signal to form a Doppler signal.
