Santos, P.2014-10-102014-10-102009AUT: PJS01028;http://hdl.handle.net/10400.1/5273Rep 02/09 - SiPLAB January/2009The main objective of this report is to present a particle velocity-pressure joint data model and a version of Bartlett estimator in order to include the particle velocity in Matched- eld inversion tecnhiques. Both data model and estimator will be used in the estimation of bottom parameters such as: the compressional wave speed, the compressional attenuation and the density of sediment, where the simulations results are pro- vided by the TRACE ray tracing model, capable for particle velocity outputs.engreport
