Microwave sensing of bulk electrical properties of tank track pad rubber

Abstract : This program was initiated to develop a nondestructive test to measure the average electrical conductivity of tank and pad rubber. The conductivity of tank pad rubber is related to the consistency of the rubber. The recommend test consists of relating the measured reflection coefficient of the tank pad to the tank pad conductivity. The reliability and effectiveness of the test is being evaluated, and the measurement interpretation process is being automated.
