✦ Synopsis
of the delay time of the correlator allow us to retrie¨e the temperature profile along an LCPW of length 2 cm deposited on alumina. In the present situation, due to a bandwidth limited between 2 and 4 GHz, the spatial resolution of temperature retrie¨al is about 4 mm. We show in this paper that the application of this processing to the radiometric data obtained with four radiometers of bandwidth 2 GHz, working at 3, 35, 60, and 94 GHz, the spatial resolution, with an LCPW of length 1 mm, becomes 200 m. These interesting results lead to the definition of a synthetic bandwidth correlation radiometer, and to a demonstration of the feasibility of a new thermometric microsensor.
