A radar sensor includes an antenna that emits a high-frequency (62 GHz) transmitted signal . This transmitted signal also includes a modulated signal with a lower frequency (10 MHz). This sensor gets the signal once it is returned back from an object.
Read moreWhat is millimeter wave technology?
Millimeter waves are also known as extremely high frequency (EHF). It’s a radio frequency that would allow transmission frequencies between 30 GHz and 300 GHz , compared to 5 GHz frequencies used by previous mobile devices.
Read moreWhat is the millimeter wave radar?
Millimeter wave (mmWave) is a special class of radar technology that uses short- wavelength electromagnetic waves . Radar systems transmit electromagnetic wave signals that objects in their path then reflect. By capturing the reflected signal, a radar system can determine the range, velocity and angle of the objects.

Due to atmospheric attenuation, millimeter radars are limited to short-range applications: about 5 km for a 94 GHz transmission . They are particularly useful in bad optical visibility: fog, smoke, dust.
