Radar is a broad term for systems that use radio waves to detect objects and measure their distance, Geschwindigkeit, and direction. Millimeter wave (mmWelle) radar is a type of radar that operates specifically in the millimeter-wave frequency band, Normalerweise dazwischen 30 GHz und 300 GHz, offering higher resolution and accuracy due to shorter wavelengths.
The detection range of mmWave radar sensors varies based on their design and application.
Millimeter wave radar offers high resolution, kompakte Größe, robust performance in harsh conditions, privacy protection by avoiding image capture, and non-contact sensing ideal for smart offices and smart hotels.
Despite their advantages, mmWave radars are limited by their need for line-of-sight, reduced performance in rain, and weaker object classification compared to optical sensors.
Ja, mmWave radar is valuable for applications requiring precise, non-contact sensing in various environmental conditions. Its ability to provide accurate measurements without compromising privacy makes it suitable for occupancy detection, space optimization, security control, and smart home devices.
