77 GHz automotive anti-collision radar used for meteorological purposes

An always-growing number of cars are equipped with radars, mainly used for drivers and passengers' safety. In particular, according to European Telecommunications Standards Institute (ETSI) one specific frequency band is dedicated to automatic cruise control long-range radar operating around 77 GHz (W-band). After the discussion of the Mie scattering formulation applied to a weather radar working in the W-band, the proposal of a new Z-R equation to be used for correct rain estimation is given. Functional requirements to adapt an automatic cruise control long-range radar to a mini-weather radar are analyzed and the technical specifications are evaluated. Results provide the basis for the use of a 77 GHz automotive anti-collision radar for meteorological purposes.
