Technical Field

[0002] Radar wave sensor is a sensor that uses radar technology to detect and measure objects, obstacles or moving targets in the surrounding environment. They determine the position, distance, speed and other characteristics of the target by emitting radar waves and detecting their reflections. It can be divided into three main steps: emission, reception and signal processing. Radar wave sensors are usually able to work in complex environments.
