The millimeter wave RADAR is an extremely valuable sensing technology ideal for detection of objects and providing information on range, velocity and angle of these objects. mmWave Technology uses a contactless technology which operates in the spectrum between 30GHz and 300GHz.

Since the millimeter wave radar (mmWave Technology) uses small wavelengths, it can provide sub-mm range accuracy and is able to penetrate materials such as plastic, drywall, clothing, and is impervious to environmental conditions like rain, fog, dust and snow.

mmWave sensors transmit signals with a wavelength which is in the millimeter (mm) range. This is considered a short wavelength in the electromagnetic spectrum and is one of the advantages of this technology. Indeed, the size of system components such as antenna required to process mmWave signals is small. Another advantage of short wavelengths is the high resolution. A mmWave system that resolves distances to wavelength has accuracy in the mm range at 60-64 GHz and 76-81 GHz.
