Description

В ОСНОВНОМ авт. св. № 133923 описано устройство дл  обнаружени  слабого пробо  в волноводе по отраженному сигналу при подаче в волновод мощных СВЧ импульсов.BASIC Auth. St. No. 133923 describes a device for detecting weak breakdown in a waveguide using a reflected signal when high-power microwave pulses are applied to a waveguide.

Предлагаемое устройство аналогичного назначени  построено на тех же элементах, что и известное устройство, но отличаетс  применением переменной реактивности и фазометрической схемы, что позвол ет нар ду с фактом определени  пробо  определить и место пробо  путем сравнени  фаз зондирующих сигналов, отраженных от места пробо  и от переменной реактивности, производимого на двух различных частотах зондирующего сигнала.The proposed device of similar purpose is built on the same elements as the known device, but differs in the use of a reactivity variable and a phasometric scheme, which allows, along with the fact of determining the sample, to determine the place of the sample by comparing the phases of the probing signals reflected from the place of the sample and from the variable reactivity produced at two different frequencies of the probing signal.

Устройство (см. чертеж) содержит магнетронный импульсный генератор / (источник мощности), разв зывающий ферритовый вентиль2 балансную фильтровую схему 3, клистронный генератор 4 (источник зондирующих сигналов), ферритовый циркул тор 5, измерительную линию 6 (фазометрическа  схема), измерительный усилитель 7 с индикаторной детекторной секцией 8, осциллограф 9, согласованную нагрузку 10 на высокий уровень мощности и переменную реактивность Л.The device (see drawing) contains a magnetron pulse generator / (power source), a balanced filter circuit 3, a klystron generator 4 (a source of probing signals), a ferrite circulator 5, a measuring line 6 (a phasometric circuit), a measuring amplifier 7 with indicator detector section 8, oscilloscope 9, matched load 10 at high power level and variable reactivity L.

Дл  компенсации прохода в фазометрическую схему импульсов магнетрона в устройстве применен компенсационный канал, включен- .ный между схемой 6 и каналом источника илшульсной мощности и состо щий из направленных ответвителей 12, переменных аттенюаторов/3 и регулирующего фазовращател  14. Импульсы магнетрона попадают в испытуемый волновод 15 и создают пробой на том участке волновода, где имеетс  дефект. Одновременно непрерывный сигнал от клистронного генератора, работающего на частоте, отличной от частоты магнетрона , попадает в исследуемый волновод и отражаетс  от ионизированного участка в месте пробо . Этот же сигнал отражаетс  и . от переменнойTo compensate for the passage of the magnetron pulses into the phase metering circuit, the device uses a compensation channel that is connected between the circuit 6 and the source channel of the pulse power and consists of directional couplers 12, variable attenuators / 3 and a control phase shifter 14. The pulses of the magnetron enter the test waveguide 15 and create a breakdown on that part of the waveguide where there is a defect. At the same time, a continuous signal from a klystron generator operating at a frequency different from the frequency of the magnetron enters the waveguide under study and is reflected from the ionized portion at the sample site. The same signal is reflected and. from variable

Определение места пробо  производитс  путем сравнени  фаз сигналов, отраженных от переменной реактивности и ионизированного участка дл  двух различных частот зондирующего сигнала.reactivity, the period of change of which is equal to the period of repetition of probe pulses. Sampling is performed by comparing the phases of the signals reflected from the variable reactivity and the ionized region for two different frequencies of the probe signal.
