Abstract

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 of 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.

First claim

That which is claimed is:

1. A method for enhancing contrast resolution of an imaging or sensing system, comprising:
receiving information from an array of transducers using multiple data channels;
digitally filtering the received information on the multiple data channels using respective finite impulse response (FIR) filters corresponding to respective data channels, the FIR filters having multiple taps, the taps including tap weights determined (1) as a function of a distance…
