DEVICE FOR MEASUREMENT OF ANTENNA DIRECTIVITY DIAGRAM PARAMETERS Russian patent published in 2017 - IPC G01R29/10 

FIELD: radio engineering, communication.

SUBSTANCE: device for measuring the antenna directiviy diagram parameters contains the series-connected testing antenna, the phase shifter, the wave T-branch, the measuring receiver, the coder and processing and control device, the fourth, the fifth and the sixth inputs of which are respectively connected to three outputs of the matching unit, the input of which is the output of the guiding and tracking devices, series-connected the first shaft-code sensor, the first tracking drive and the rotary table of the receiving antenna azimuth rotation, which is mechanically connected to the receiving antenna horizontal axis of rotation and the first shaft-code sensor, series-connected the second shaft-code sensor, the second tracking drive and the rotating table of the angular inclination of the receiving antenna, which is mechanically connected to the receiving antenna angular axis of rotation and the second sensor shaft-code and also containing the synchronizer, three outputs of which are connected respectively to the second inputs of the measuring receiver, the coder and processing and control device, the first output of which is connected to the second phase shifter input, the second output to the second input of the first tracking drive, the third output - to the second input of the second tracking drive, and the third and the seventh inputs are respectively connected to the second outputs of the first and the second tracking drives. Additionally introduced the series-connected the synchronization signal reception device and the shaper of measuring strobes, the first output of which is connected to the first input of the electronic switch, the second-with the first input of the meter, and the third output - with the signal generator input, which output is the second input of the electronic switch, the first output of which is connected to the second input of the meter and the second output- with the input of the auxiliary antenna, which is the third output of the electronic switch, as well as the associated along the radio channel with the synchronization signal reception device, the synchronization signal transmission device, which input is the fourth output of the synchronizer, and the transmitting device, which output is the input of the testing antenna, and the input is connected to the fourth synchronizer output.

EFFECT: improvement of the accuracy and informativity of the antenna radiation diagram parameters measurements due to operation synchronization of the measuring devices and sources of device measurement signals for reception/transmission in the temporary area.
