Abstract:

An investigation has been carried out into the effects of wireframe detail and model subprocessing on the predicted optical frequency OF signature of a platform. This report describes the results of that investigation. Overall it is concluded that to be able to compare the computed OF signatures of different platforms with validity, the models of the platforms have to incorporate the same level of wireframe detail, especially in internally-heated regions such as their stacks. They also have to be processed using subdivisions of very similar size, based on the same method of facet subdivision.
