Impact on the Computation of the Medium MTF by Estimation of the Total Scattering Coefficient
2007
Estep, L.
Using both sea water data and research tank water data, coupled with the theoretical approach of Wells, calculations of the modulation transfer function (MTF) for the water medium are performed via use of the Wells Decay Function. Various approximate relationships are used to derive the value of b, the total scattering coefficient, which enters into the MTF calculation. The approximate b values are used to compute the water MTF. These estimated MTF calculations are compared with experimental data MTF calculations for which the actual water value of b was derived. Error assessments and recommendations for the various b relationships used in the MTF computation are made.... Air defense initiative, Acoustic modeling, Oceanography, Antisubmarine warfare.
