Abstract
A microwave thermography apparatus to measure temperatures within a dielectric body comprises a partial ellipsoidal cavity with an electrical conductive surface wherein the body can be located at one focus of the cavity. A microwave antenna located at a second focus of the cavity is connected to a radiometer. That radiometer amplifies and filters signals from the antenna before they are applied to a detector with the temperature of the body being determined from the voltage amplitude of the detected signals.
