RADIOMETRIC REGISTRATION OF WEAK BROADBAND RADIO SIGNAL Russian patent published in 2011 - IPC G01R23/16 

FIELD: physics.

SUBSTANCE: proposed method uses measurement of signal differential power in broadband receiving channel. Received signals in broadband channels are converted in sequences of digital samples and Fourier analysis is used to calculate and accumulate power spectra to rule out spectral components exceeding preset values and sum remained spectral components. In accumulating radio telescope natural noise and radio interferences calculated via power spectra of received signal mix, fluctuations of spectral components are smoothed out to make noticeable weak narrowband radio interferences. Comparison of power calculated after elimination of spectrum components in radio interference frequency with radio telescope natural noise outputs analysed signal power.

EFFECT: higher accuracy of measurement.
