Introduction to Millimeter Wave Radar Technology
Anton Varavin

Millimeter wave (mmWave) is a special class of radar technology that uses short-wavelength electromagnetic waves. Radar systems transmit electromagnetic wave signals that object in their path then reflect. By capturing the reflected signal, a radar system can determine the range, velocity and angle of the objects. mmWave radars transmit signals with a wavelength that is in the millimeter 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 the antennas required to process mmWave signals is small. Another advantage of short wavelengths is the high accuracy. A mmWave system operating at 76–81 GHz (with a corresponding wavelength of about 4 mm), will have the ability to detect movements that are as small as a fraction of a millimeter. A complete mmWave radar system includes transmit (TX) and receive (RX) radio frequency (RF) components; analog components such as clocking; and digital components such as analog-to-digital converters (ADCs), microcontrollers (MCUs) and digital signal processors (DSPs).

That is a pretty fascinating overview of what can be determined from mm radar measurements! One question I had was what type of maximum range does a typical conventional mm radar system have? Does it measure over several meters, or can it make measurements over 100s of meters? Thank you.

This looks really interesting - mixing natural analogue with artificial bits ... I'll feedback once I've reviewed slides ... could take a few days with EOC2023 in progress. Thanks!
