METHODS AND APPARATUS FOR AUTOMOTIVE RADAR SENSORS

摘要

Methods and apparatus are presented that reduce the overall system cost for automotive radar sensing applications through reduction of the number of the radar sensors required. In accordance with aspects of the present invention, one way sensor count reduction can be achieved is through the combination of target range, direction, and velocity determination capability with wide angular field of view coverage within a single sensor unit. One embodiment combines a wide field of view antenna means with a wideband / ultra-wideband / precision-ultra-wideband radar transmitter-receiver and an interferometric direction-finding means into a single sensor unit. Other methods and apparatus are presented.
