Composite body armors are subjected to extreme in-service and environmental stresses, such as extreme temperature changes. Evaluating body armor property e.g., materials and thickness, in particular variations of thickness from its nominal value, is of great interest. Microwave nondestructive testing and evaluation techniques NDT and E, using open-ended rectangular waveguide probes have been successfully developed and used for evaluating materials properties and thickness in stratified composite structures, which are similar to a body armor, and even those that are significantly more complex in design. Microwave NDT and E techniques have improved and advanced over a period of more than two decades during which the efficacy of the analytical formulations and measurement tools significantly increase the accuracy associated with this type of evaluation. This technique was used in this study to evaluate body armor properties. Additionally, the efficacy of the wideband frequency-modulated continuous-wave radar approach was demonstrated on a limited basis to illustrate its potential utility for thickness evaluation.
