FIELD: electricity. ^ SUBSTANCE: detect the signal accepted by the aerial SHF detector, refer on the balancing modulator and make its disbalance, receive the changed potential proportional to the accepted signal, filter the concentrated selectivity with a filter, strengthen the potential amplifier, detect again and register the indicator of magneto-electric system of a direct current. The device contains quartz generator (heterodyne), resonant reception aerial, first SHF detector, balancing modulator, frequency filter of the concentrated selectivity, amplifier, second detector and indicator. ^ EFFECT: sensitivity rising, expansion of range of measurement and power consumption decrease ^ 2 cl, 2 dwg |
