VORAD collision warning radar

This paper discusses the use of radar technology for collision warning and other vehicular applications. Radar design difficulties and trade-offs regarding operating frequencies, frequency bandwidth requirements, transmitted power and the use of existing low cost production components are presented. The first commercial production radar system to be marketed, the VORAD system, is discussed and the theory of operation of this radar system is described. A discussion of existing FCC regulations as related to intentional radar radiators and future FCC considerations is provided as well as some insight into international regulatory considerations.
