Method and apparatus for processing of the echo signals in a coherent imaging system

摘要

described are a method and an arrangement for improved digital processing of the analog echo signals (18, 24) in a coherent imaging system (10) which demands on the kanalschaltungsanordnung simplify.the analog echo signals (18 to 24), with a phased matrix of wandlerelementen (e1 - en), are first compressed and then nonlinear way with analog / digital wandlereinrichtungen (50, 56) nonlinear expanding to an enlarged augenblicksdynamikbereich i n the overall system.
