UAF Patent # 8,554,816
describes a filter which cleans digital signals and resolves the cocktail party effect. This technology focuses a listener’s attention on a single sound among a mixture of background noises, while ignoring other conversations.
racking a moving signal by passive methods has been difficult due to the Doppler shift that is introduced into the observations of each sensor. The system and method described in
overcomes the complications of Doppler shifting in signal source tracking.
Using a passive sensor array to determine the position of a signal source has proven difficult, and many techniques are only designed for application with sensor arrays of specific, symmetrical geometries.
protects a fast method of determining the location of a signal source.
