Forward-looking automotive radar using a W-band single-chip transceiver

A prototype W-band all-weather automotive radar based on a single-chip 0.1-/spl mu/m AlGaAs-InGaAs-GaAs HEMT transceiver has been developed. This radar has the features of simple architecture and small size, with adequate performance. Owing to the maturity of HEMT MMIC technology, this radar is potentially low cost to implement in personal vehicles. The prototype radar used for autonomous intelligent cruise control in a passenger car is presented in this paper. The MMIC development, together with the radar system design, is also addressed.<
