James B. Donald is an accomplished inventor based in Pawcatuck, CT (US). He holds a total of 5 patents that showcase his expertise in noise suppression and sonar tracking technologies. His contributions have significantly advanced the fields of acoustics and underwater detection.

Latest Patents

One of his latest patents is a noise suppression system. This invention provides a method and apparatus for suppressing noise by receiving a plurality of signals from an array of sensors and transforming these signals to the frequency domain. The transformed signals are then beamformed to identify noise sources by bearing and frequency range. A planewave-fit noise-suppression routine is utilized to remove identified noise sources from the transformed signals, resulting in a noise-suppressed transformed signal.

Another notable patent is a tracking system and method of operation. This invention detects, processes, and tracks sonar signals to provide bearing, range, and depth information, effectively locating an object in three-dimensional underwater space. The Twenty Six Nearest Neighbor Peak Picker (TSNNPP) improves the detection of signals in noisy backgrounds by differentiating the bandwidth characteristics of signals from those of noise.
