Title:
SENSOR SYSTEM, VEHICLE PROVIDED WITH SAME, AND RADIO WAVE TRANSMISSION/RECEPTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/106136
Kind Code:
A1
Abstract:
Provided are: a sensor system for controlling a sampling frequency of an electromagnetic wave emitted by a radio wave sensor to reduce power consumption; a vehicle provided with the same; and a radio wave transmission/reception method in the sensor system. A sensor system (1) is configured by including a radio wave sensor (2), a vibration sensor (3), and a signal processing device (4). The radio wave sensor (2) emits a radio wave toward a measurement target (5), receives a reflected wave, and outputs reflected-wave data to the signal processing device (4). The vibration sensor (3) detects vibration superimposed as noise on the reflected wave received by the radio wave sensor (2) and outputs detected vibration data to the signal processing device (4). A sampling frequency setting unit (4a) of the signal processing device (4) recognizes a frequency range of vibration to be detected by the vibration sensor (3) to specify an upper limit of the frequency range, and sets a sampling frequency of the radio wave to be emitted by the radio wave sensor (2) to the sampling frequency having the specified upper-limit frequency as a Nyquist frequency.
