Patent Searching and Data


Title:
RADAR DEVICE AND DISTANCE AND SPEED MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2015/098223
Kind Code:
A1
Abstract:
A radar device is provided with an ADC (7) for slide sampling a frequency difference signal output by a mixer (6) and dividing the sampling data for the frequency difference signal into each range bin for the distance resolution corresponding to a pulse width set by a control device (1), and a speed discrimination unit (10) for separating the sampling data divided into each range bin by the ADC (7) according to relative speed. A distance and speed measurement unit (11) uses the sampling data separated according to relative speed by the speed discrimination unit (10) to calculate the distance (R) to an object reflecting transmitted pulses and the speed (V) in relation to the object.
