Imaging or communications system utilizing multisample apodization and method

摘要

Methods, systems and system components for optimizing contrast resolution of an imaging or sensing system utilizing multiple channels of broadband data associated with an array of transducers. Channels or data are filtered by passing the channels of data through finite impulse response (FIR) filters on each channel. The filters each have multiple taps having tap weights pre-calculated as a function of distance of the array from an object that energy is being transmitted to or reflected from. The weights are pre-computed through a deterministic equation based on an a priori system model.

1. A method of optimizing contrast resolution of an imaging or sensing system utilizing multiple channels of broadband data associated with an array of transducers, said method comprising:
filtering the channels of data by passing the channels of data through finite impulse response (FIR) filters on each channel, the filters each having multiple taps having tap weights pre-calculated as a function of distance of the array from an object that energy is being transmitted to or reflected from, said weights having been pre-computed through a deterministic equation based on an a priori system model; and performing one of sending the filtered channels of data to the array or processing the filtered channels of data to form processed data and outputting the processed data for use by a human user.
