DEVICE FOR MEASUREMENT OF AMPLITUDE-PHASE FIELD DISTRIBUTION IN RECEIVING AERIAL APERTURE Russian patent published in 2006 - IPC G01R29/10 

FIELD: measurement engineering; amplitude-phase aerial measurements.

SUBSTANCE: device for measurement amplitude-phase field distribution in receiving aerial aperture has super-high frequency generator. Output of the generator is connected with measuring probe and with first input of amplitude-phase meter. Output of the latter is connected with first input of data collection and control device. First input of the latter is connected with first input of first computational unit intended for memorizing measured relations of signal amplitudes and phases and for computing amplitude-phase distribution. Device for measurement amplitude-phase distribution has turn unit being mechanically connected with tested aerial which has output connected with second input of amplitude-phase meter. Data collection and control unit serves for forming and outputting control commands to turn unit and for controlling measurement device in total. Device also has second computational unit intended for computing coordinates of points of measurement of tested aerial's transmission factor vector correspondingly to optimal spatial structure of measurement and memory unit intended for storing information on spatial configuration of the aerial. Output of second computational unit is connected with second input of information collection and control unit and with second input of first computational unit. Output of memory unit is connected with input of second computational unit and with third input of first computational unit. Memory unit is mounted onto tested aerial.

EFFECT: improved precision of measurement.
