View pageUS Patent:
52688771, Dec 7, 1993
Filed:
May 11, 1992
Appl. No.:
7/880824
Inventors:
Douglas L. Odell - Poulsbo WA
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:

US Classification:

Abstract:
A beamformer system is disclosed which includes an array of sensors such as ydrophones which produce signals from which information relating to a target is to be determined. The beamformer system includes a channel for each sensor, the channel including a varable length shift register which provides bulk delay to received signals, a FIR interpolation filter which provides vernier delay and shading. The system also includes a summation tree which adds the received signals and a sign extension/bit reversal filter to avoid authmetic overflow.
