  • Publication number: 20180224525
    Abstract: A vehicle radar. In the vehicle radar, a high-pass filter is disposed on a signal line connecting a transmitting chip and a receiving chip, the signal line allowing a local oscillation signal to be transferred therethrough. The high-pass filter prevents noise from being introduced through the signal line, along which the local oscillation signal is transferred. This prevents the accuracy of detection from being lowered by low-frequency noise generated from the interior of the vehicle radar. The high-pass filter connected to the signal line is embodied as a variety of configurations, thereby providing a structure able to effectively suppress low-frequency noise while maintaining the existing structure of the vehicle radar.
