A New Method for the Improvement of Frequency Resolution of Microwave Hyperspectrometers

Resumo

We propose a new original method aimed at the improvement of the frequency resolution of microwave hyperspectrometers in the SHF range for a given duration of single measurement and sensitivity. The method is based on the combined application of the multireceiver concept and the zero-measurement method. The block diagram is developed and the principle of functioning of the receiving channel of an SHF hyperspectrometer is described.
