WIDE BAND SPECTRUM ANALYSER Russian patent published in 2014 - IPC G01R23/16 

FIELD: radio engineering, communication.

SUBSTANCE: analyser is designed to be used in radio equipment of a various purpose, in particular, in radar ranging and radio intelligence. The analyser contains one dispersion and two non-dispersion delay lines. It also contains four delay lines and three mixers. Each of the non-dispersion lines is connected to its own input summation unit and amplifier. The outputs of the latter, in turn, are connected to the corresponding output of the switch. The device also contains a pulse generator, a shift modulator, a frequency-modulated heterodyne, a reference generator and two frequency filters.

EFFECT: capability of detecting and measuring parameters of linear-frequency modulated signals with an unknown carrier change rate, simplification of the manufacturing process.
