Abstract
The device comprises a microwave detector, a short-circuit microwave, a first modulator, or microwave-switch, a circulator with three successive channels, at least two sources of internal reference temperatures, a second modulator or microwave-switch, possibly an attenuator, a synchronization command circuit acting both on the first modulator and on the second modulator to obtain at least four different successive outgoing signals, a microwave detector, advantageously a microwave amplifier, and a calculator connected to the output of synchronization command circuit, said at least four successive signals being detected to deduce therefrom the temperature at the detector level, independently of the coefficient of reflection of the detector with respect to the region of the losses and of the modulators and of the cables.
