Difference between Ultrasonic Radar and Millimeter Wave Radar

The difference between these two radars is different detection range, different application scenarios and different weather effects.

1, the detection range is different: the detection distance of ultrasonic radar is close, only a few meters; Millimeter wave radar has a long detection distance, which can reach more than 200 meters.

2. Different application scenarios: Ultrasonic radar is suitable for short-distance and low-speed measurement, and is widely used in robot navigation, industrial control and other fields; Millimeter-wave radar has the characteristics of high precision, long detection distance and strong anti-interference ability, and is widely used in automobile safety system, security monitoring and other fields.

3. Different weather effects: ultrasonic radar will limit weather conditions; Millimeter-wave radar has strong penetration rate, and can accurately detect objects through illumination, rainfall, dust, smoke or frost, and can work in all-weather environment.
