Millimeter Wave Radar Sensor Power Source Circuit: Description
WARNING: This page is about a different car, the 2012 Lexus GX 460. However, it is still accessible from the selected car via links, so may be relevant.
This circuit provides power to the millimeter wave radar sensor. The millimeter wave radar sensor emits radar waves towards an object in front and measures the distance and direction of the object by receiving the beam reflections. Based on the reflections, the sensor calculates the difference in speed between the vehicle and the object in front.
