Abstract :
A method of adequate visual microwave wide-band intense noise envelope reproduction in wide frequency range (several octaves), power parameters measurement and detection of a narrow-band signal with unknown frequency and power against a background of noise is presented. It is based on application of nonheterodyne gyromagnetic converter, operating in two regimes: resonance detection and cross-multiplication. Operation of the two-channel measurer of spectrum power density combining the mentioned functions is discussed.
