    摘要: A vehicle speed sensing device comprises a Doppler radar unit for producing a Doppler signal related to the vehicle speed and producing a speed signal from the Doppler signal, a first section for extracting noise components in the Doppler signal and producing a noise detection signal, and a second section for producing an output signal of the vehicle sensing device. The device output is the speed signal from the Doppler radar unit when the noise detection signal is absent while the device output is null or a speed signal having an amplitude identical with that of the speed signal just before the appearance of the noise detection signal when the noise detection signal is present.
