Abstract:

The long term goals of this work are to develop high-resolution subbottom imaging and inversion techniques that can be complementary to low-frequency geoacoustic inversion methods. The objectives of this effort are to invert bottom geoacoustic properties along the ONR-SW06 acoustic propagation tracks by using chirp sonar data and to validate the inversion results by using wide-band acoustic probe measurements of sound-speed and attenuation.
