Abstract

A method for an adequate visualization of a microwave intense noise envelope in a wide frequency range (several octaves), measuring of its power parameters, and detection of a narrowband signal with unknown frequency and power against the noise background is presented. This method is based on an application of a nonheterodyne principle of microwave frequency (and power) conversion using a gyromagnetic converter, which operates in two regimes in turn: the resonance detection and the cross-multiplication. A block-scheme and an operation of a two-channel measuring device combining the mentioned functions are discussed.
