Abstract :
Theoretical considerations and experiments indicate how the temperature of an impedance Z(f) and its position on the line connected to the two inputs of a correlation radiometer can be deduced from the radiometric signals. Such a process should be considered for thermometric applications based on the analysis of the radiometric signal produced by a nonisothermal lossy line.
