Abstract
Official abstract text for this publication.
A wideband sonar receiver is provided that includes: a selectable bandpass filter adapted to filter a received sonar signal to produce a filtered signal and a correlator adapted to correlate the baseband samples with baseband replica samples to provide a correlated signal. In addition, the wideband sonar receiver may include a shaping filter to shape unshaped received pulses. Finally, a variety of sonar processing algorithms are described with regard to reducing clutter and interference, target detection, and bottom detection.
First claim
Opening claim text (preview).
What is claimed is: 1. A wideband sonar receiver, comprising: a selectable bandpass filter adapted to filter a received sonar signal to produce a filtered signal; an analog-to-digital converter for converting a version of the filtered signal to provide digitized samples; a digital basebanding and decimation stage adapted to baseband and decimate the digitized samples to produce baseband samples of the received sonar signal; and a correlator adapted to correlate the baseband…
