Abstract:
A software package was developed to provide the inputs for a passive single-sensor acoustic tracker. This required a computation of sound propagation velocity and resolving high-resolution frequency information from raw acoustic data. A selected frequency was then automatically tracked from an up-doppler to a down-doppler condition. This frequency information coupled with associated bearing information was then used to provide continuous target fixes. Author
