Zusammenfassung:	FIELD: monitoring devices for safety services with various goals. ^ SUBSTANCE: result is achieved by introduction of first quadrature auto-compensator for removing background voltage in receiving route of observation device and due to aforementioned increase of its amplification coefficient; by introduction of second quadrature auto-compensator - for finding small amplitude-phase fluctuations of signal in receiving route of finding device. ^ EFFECT: increased sensitivity of device with limited power of radiation. ^ 2 dwg
