[0002] Radar sensors need to process signals of different frequencies when working, so the circuits on the circuit board usually contain frequency adjustment circuits and filters to select signals within a specific frequency range, eliminate interference signals, and ensure the accuracy and stability of the radar sensor. The circuits on the circuit board can receive and amplify the weak echo signals received by the radar sensor. The signals come from the microwaves or millimeter waves emitted by the radar and the signals returned after being reflected by the target object. They need to be amplified and processed before they can be effectively analyzed and used.
