description FIELD: radio engineering; receiving radars, radio navigation and radio communication devices. ^ SUBSTANCE: current estimate of noise dispersion parameter used for shaping oscillation limitation level at output of broadband amplifier 2 is calculated at low input signal-to-noise ratio using sample of adaptive input signal and noise mixture. Device also has digitizer 1, limiter 3, narrow-band amplifier 4, squarer 5, square-root calculator 6, amplifier 7, adder 8, integrator 9, first and second amplifiers 10, 13, accumulator 11, and divider 12. ^ EFFECT: enhanced efficiency of weak signal detection in adaptive broadband noise background under conditions of a priori uncertain statistical noise characteristics. ^ 1 cl, 1 dwg
