Description
Известны устройства в аэроэлектроразведке дл измерени отношени (разности) амплитуд и сдвига фаз двух переменных напр жений , содержащие усилители, фильтры, регистраторы.Airborne electrical devices are known for measuring the ratio (difference) of amplitudes and phase shifts of two alternating voltages, containing amplifiers, filters, recorders.
Эти устройства из-за малой чувствительности и помехоустойчивости более пригодны дл абсолютных, чем дл относительных измерений .These devices, due to their low sensitivity and noise immunity, are more suitable for absolute than for relative measurements.
С целью повышени чувствительности и помехоустойчивости при аэроэлектроразведочных измерени х, согласно изобретению, предложено устройство, имеющее общий входной коммутатор и единый избирательный усилитель рабочей частоты на входе и два переключател на выходе, работающие синхронно с входным коммутатором.In order to increase sensitivity and noise immunity in aero-electrical measurement, according to the invention, a device is proposed having a common input switch and a single selective input operating frequency amplifier and two output switches operating synchronously with the input switch.
На чертеже изображена блок-схема устройства.The drawing shows a block diagram of the device.
Сигналы с приемных рамок усиливаютс гондольными усилител ми/и 2. Напр жение Vy , снимаемое с выхода гондольного усилител 2, поступает на усилитель-ограничитель 3 и затем подаетс на вход фазочувствительного детектора 4. Опорным напр жением дл фазочувствительного детектора служит сигнал, полученный от переключател Ki.The signals from the receiving frames are amplified by the nacelle amplifiers / and 2. The voltage Vy taken from the output of the nacelle amplifier 2 is fed to the amplifier-limiter 3 and then applied to the input of the phase-sensitive detector 4. The reference voltage for the phase-sensitive detector is the signal received from the switch Ki.
На нагрузочном сопротивлении при отсутствии фазового сдвига между напр жени ми Уу и V,, будет создаватьс только некотора посто нна составл юща , обусловленна посто нным (или медленно мен ющимс ) фазовым сдвигом Афоз избирательного усилител рабочей частоты 5 и усилител -ограничител . Это посто нна задерживаетOn the load resistance, in the absence of a phase shift between the voltages Uy and V, only a certain constant component will be created, due to the constant (or slowly varying) phase shift Ahoza of the selective operating frequency amplifier 5 and the limiting amplifier. This is a constant delay.
