    摘要: A process and apparatus to automatically determine whether a police radar is installed in a vehicle which has a coupling between a vehicle speed sensor and the police radar. The process automatically, without any operator input, determines the correct ratio between the true ground speed and the frequency output by vehicle speed sensor at that ground speed. The process and apparatus then use that ratio and the frequency from the vehicle speed sensor to establish a software search window that limits the speed range of the search by the police traffic radar for the true ground speed.

    摘要: A device for non-contractual measurement of the speed of an object moving over a surface comprises a means for radiating a signal of fixed frequency at an angle onto the surface in or against the direction of motion, said angle being variable by the movement of the object, and for receiving a Doppler-shifted signal reflected at the surface. A means is provided for combining a plurality of reflected Doppler-shifted signals, which are received in temporal succession, so as to produce a combined spectrum. The device for non-contractual speed measurement additionally comprises a means for detecting from the combined spectrum the spectral portion having the highest or lowest frequency and exceeding a predetermined signal power, and a means for deducing the speed from the frequency of the detected spectral portion.

    摘要: The present invention is a method of deriving a ground speed of an aircraft on a descent along a flight path. A vertical speed signal is produced as a function of an altitude signal and a vertical acceleration signal. The vertical speed signal is transformed to a nominal ground speed signal based upon a glide slope defined by a glide slope beam. A correction is produced based on a glide slope deviation rate representative of deviation of the aircraft from the glide slope. The nominal ground speed signal is corrected with the correction to produce a corrected ground speed signal. The corrected ground speed signal is filtered with a horizontal acceleration signal and a runway heading signal to produce a smoothed ground speed signal.

    摘要: The invention concerns a method and a device to measure the speed (v) of a vehicle relative to a road surface. To increase the accuracy of the speed measurement and in order to be able to determine the speed (v) of the vehicle independently of the diameter and the adhesion of a vehicle wheel on the road surface, the invention proposes that the speed (v) of the vehicle is measured directly on the road surface by utilizing the Doppler effect.

    摘要: An FM-CW radar is provided which may be employed in anti-collision systems or cruise control systems installed in moving objects such as automotive vehicles. The radar produces a first spectrum using a portion of a beat signal in a frequency rising range wherein the frequency of the radar wave increases and a second spectrum using a portion of the beat signal in a frequency falling range wherein the frequency of the radar wave decreases and moves the second spectrum by frequency shifts which are determined as a function of the speed of a radar-mounted vehicle and corrected for compensating various errors involved in measuring the speed of the vehicle to form spectrum groups each consisting of the frequency components moved by one of the corrected frequency shifts and frequency components in the other of the first and second spectra. The radar selects an optimum one of the spectrum groups for use in determining target data.
