Изобретение относитс  к антенной технике СВЧ диапазона, в частности к измерительным устройствам дл  определени  пространствениого распределени  фазы злектромагнитного пол ..The invention relates to microwave antenna technology, in particular, to measuring devices for determining the spatial distribution of the phase of an electromagnetic field.

Известно устройство дл  измерени  фазового распределени  осесимметричного пол , содержащее диэлектрическую апертуру и волноводный зонд с квадратичным приемником.A device for measuring the phase distribution of an axisymmetric field is known, comprising a dielectric aperture and a waveguide probe with a quadratic receiver.

Однако известное устройство не позвол ет проводить измерени  на поверхности диэлектрика без искажений измер емого пол .However, the known device does not allow measurements on the surface of the dielectric without distortion of the measured field.

Предлагаемое устройство отличаетс , тем, что диэлектрическа  апертура ограничена непрозрачной диафрагмой с круглым отверстием , соосным с полем, а зонд расположен в дальней зоне на оси пол , причем край диафрагмы формирует исследуемое поле, а опорным -сигналом служит пр мое излучение апертуры .The proposed device is different in that the dielectric aperture is limited to an opaque diaphragm with a circular hole coaxial with the field, and the probe is located in the far zone on the axis of the floor, the edge of the diaphragm forming the field under study, and the reference signal is the direct radiation of the aperture.

На чертеже представлена функциональна  схема устройства.The drawing shows the functional diagram of the device.

Устройство содержит диэлектрическую -апертуру /, волноводный зонд 2 с квадратичньгм приемником в виде детектора 3. Диэлектрическа  апертура ограничена непрозрачной диафрагмой 4 с круглым отверстием 5, соосным с полем, причем край диафрагмы формирует исследуемое поле, а опорным сигналом служит пр мое излучение апертуры. Оба сигнала принимаютс  открытым концом волновода - волноводним- зондом 2 и поступают на детектор 3. Сигнал от детектора подаетс  на при-бор 6.The device contains a dielectric aperture /, a waveguide probe 2 with a quadratic receiver in the form of a detector 3. The dielectric aperture is limited to an opaque diaphragm 4 with a circular aperture 5 coaxial with the field, the edge of the diaphragm forms the field under study, and the reference signal is the direct radiation of the aperture. Both signals are received by the open end of the waveguide, waveguide probe 2, and are fed to detector 3. The signal from the detector is fed to the instrument 6.

Волноводный зонд расположен В дальней зоне на оси пол  на рассто нии многих длин волн от поверхности диэлектрика и диафрагмы . ТаКим образом достигаетс  требуема  разв зка между зондом и поверхностью диэлектрика .The waveguide probe is located in the far zone on the floor axis at a distance of many wavelengths from the surface of the dielectric and diaphragm. In this way, the desired separation between the probe and the surface of the dielectric is achieved.

При измерени х волноводный зонд движетс  вдоль оси с помощью устройства 7.When measuring, the waveguide probe moves along the axis using device 7.
