Recently, terahertz ray (T-ray) imaging emerged as one of the most promising techniques to inspect the space shuttle external tank foam insulation. This paper demonstrates the application of state-of-the-art computer processing and modeling technologies to assist in further refinement of this new technology. The current protocol of T-ray inspection and its limitations are first reviewed. New strategies of using signal processing and modeling are then proposed to improve on the flaw detection. Preliminary results are presented on a series of multi-dimensional signal processing operations of T-ray signals. The use of models and their comparisons with experimental data from foam samples are also included.
