ABSTRACT:
A method for measuring the physical temperature of objects by means of microwaves using a Dicke radiometer. A noise signal is continuously applied to an antenna which is directed towards the object and is periodically and alternately applied, together with the antenna signal, which includes reflected noise and object emission to the radiometer. The integrated output signal of the radiometer controls the noise power and is proportional to the object temperature.
