79 GHz High Resolution Short Range Automotive Radar Evolution

摘要

The 79 GHz band (77 to 81 GHz) was identified in Europe as the most suitable frequency band for long-term and permanent deployment of high resolution automotive radars due to its benefits. This article highlights the applications and benefits of 79 GHz, motivating a harmonized regulation for the 77 to 81 GHz band as a stable, permanent and globally harmonized frequency band for high resolution automotive radar equipment; and illustrates the status of allocation of the 77 to 81 GHz band in the key countries around the world and the current on-going initiatives for regulation.
