MCCAVITY

McCavity is used for the modelling of whole aircraft signatures with plumes, and specialises in modelling the complex radiative interactions that occur within aerial vehicle intake and exhaust cavities.  McCavity can be used to analyse the contribution of individual engine components to the IR signature, providing invaluable options to modify any components in order to achieve a lower observability.  Both inband and line-by-line solutions are possible.  Hyperspectral thermal images of an aircraft can be rendered from any given observer position, with atmospheric effects included. An overall distribution of the thermal radiation emitted from a cavity can also be generated over an exit hemisphere to identify viewing angles with high signatures.
