Paper Abstract

Thermography has been available for some time as an aid in the determination of temperature differentials. Burton, et al, have demonstrated that thermographic techniques may be used qualitatively to detect induced surface currents resulting from impinging Electromagnetic (EM) waves on particular shapes. The surface currents are detectable because of the energy deposited on the object in the form of I2R heating. A knowledge of the induced surface currents is invaluable to the study of radar cross section reduction and Electromagnetic Pulse (EMP) absorption. Therefore, a method is presented which provides a method of determining the temperature distribution on a complex shape subjected to microwave radiation. Thermographic detectors are either energy detectors (thermocouples) or photon detectors (semiconductors). A model is developed for each type which describes the infrared emission detection associated with a complex shape.
