Abstract:

The report describes a FORTRAN IV computer code, BOTREF, which calculates the bottom reflection pressure history of underwater explosion shock waves. The reflection is computed for incident exponential pulses and plane, homogeneous, elastic bottoms using a linear spherical wave theory. Corrections for the non-linear variations of the peak pressure and time constant with distance are included. The program generates a plot tape for use on CALCOMP incremental plotters. Provisions are made for incorporation of the machine program that calculates the peak translational velocity of a ship target described in NOLTR 71-65. For comparison, an option is included for calculating the bottom reflection using the plan wave theory instead of that for spherical waves.
