Particle filtering for passive fathometer tracking [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2011
Seabed interface depths and fathometer amplitudes are tracked for an unknown and changing number of sub-bottom reflectors. This is achieved by incorporating conventional and adaptive fathometer processors into sequential Monte Carlo methods for a moving vertical line array.
