Abstract
A method for detecting fixed or moving objects within an angular zone, as may be used in vehicle anti-collision systems, employs separate and distinct transmission and reception patterns. The transmission pattern successively illuminates consecutive segments of the angular zone. The reception pattern receives echo signals in parallel from illuminated objects in each zone segment. The echo signals are then digitally beam formed into a total field signal. The angular positions of the detected objects are then derived from the total field signal.
