Radar-based products have flourished through the sensor market due to their benefits in detecting motion. Radar accommodates indoor and outdoor applications because the performance of the detection is not affected by weather conditions like rain, snow, or fog. It also works in the dark and in challenging light conditions. Radar devices also can be used in harsh environments: dust, vibration, noise, heat or cold do not affect object measurement. Radar is an anonymous and touchless measurement technology. Radar waves can radiate through a wide range of materials, making it optimal for concealed applications. Vandalism like graffiti or chewing gum in front of the antenna does not affect detection. Once set up is complete, no regular maintenance is required. The sensor detects objects, people, or vehicles at extended distances. This makes radar one of the most reliable and robust measurement technologies.
