Abstract

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 transmit-pulsed, linearly stepped frequency modulated, transmit power limited radar architecture with a spatially separated receiver antenna array, intermediate frequency down-conversion, and a digital multi-zone monopulse (DMM) signal processing technique for high-resolution target range, velocity, and azimuth angle determination and fast update rate capability in a low cost, mass-production-capable design.
