Abstract
The development and incorporation of the latest enhancements to the AVAST code are described. The purpose of this work was to make the modeling of the physical environment more realistic, while ensuring that the code runs as efficiently as possible. To this end several new features have been added. These include modifying the high-frequency Kirchhoff scattering method in order to allow for at least one reflection and upgrading the existing boundary element surface panel integration routines. The contract also addresses the need to investigate the high frequency target strength of Manta shapes.
