Where is the radar sensor installed on the Santana?

[EllaAnn]

The radar sensors on the Santana are installed 10 centimeters to the left and right of the license plate, facing directly forward and backward, primarily for detecting objects in front of and behind the vehicle. The sensors on the left and right sides are installed at the corners of the car, angled outward by 20 to 30 degrees, mainly to prevent corner collisions. More information about radar sensors is as follows: 1. Ultrasonic sensors can be divided into two types: electric ultrasonic and mechanical ultrasonic. Currently, the more commonly used type is the piezoelectric ultrasonic sensor, which consists of two piezoelectric crystals and a resonance plate. 2. When the frequency of the piezoelectric crystal matches its natural oscillation frequency, the piezoelectric crystal resonates and drives the vibration of the resonance plate, thereby generating ultrasonic waves. Conversely, if the resonance plate receives ultrasonic waves, the piezoelectric crystal is subjected to pressure, converting mechanical energy into an electrical signal. At this point, the piezoelectric crystal functions as an ultrasonic sensor.
