Adaptive Algorithm and Software for Recognition of Ground-based, Airborne, Underground, and Underwater Low Frequency Events
An issued NASA patent from the Technology Transfer catalog.
About this technology
Overview
The innovative approach is to exploit modern signal processing methods. i.e. adaptive filtering, where the computer is trained on-line to recognize features of the low frequency events (on the ground, in air, underground, and underwater) to be detected. Modern instrument development techniques and computational capability has enabled the development of a vastly more powerful algorithm and detection techniques.
