The traditional Ka antenna phase calibration generally adopts manual phase calibration, and the test steps can be as follows: starting testing at 8-9 am every day, correcting the system by using a tracking receiver, recording phase values, manually correcting the phase at different temperatures (the temperature difference is more than 10 ℃), and repeatedly and continuously testing for multiple days to obtain the phase correction value at the required temperature; the phase change values of the calibration phases at different temperatures are recorded and compared. The phase calibration method has long duration, human interference is needed for tracking and calibrating the phase each time, the labor cost is high, and the phase calibration method is inconvenient to test at night, so that the data integrity is poor. Aiming at the defects existing in manual phase calibration, the embodiment of the invention provides a method for testing the change of the tracking phase value of a Ka antenna, which is used for obtaining the change of the tracking phase by processing azimuth error voltage data and pitch error voltage data of the antenna recorded at different moments. Because the azimuth error voltage data and the pitch error voltage data of the antenna are original data which can be directly and automatically recorded, and the phase value is not the original data which can be directly recorded and needs to be obtained by manual calibration, the method for obtaining the change of the tracking phase by processing the azimuth error voltage data and the pitch error voltage data of the antenna recorded at different moments does not need manual intervention, does not need to increase testing equipment and instruments, does not need to consider testing time (which can be carried out at night), is simple, convenient and reliable, and improves the testing efficiency. Furthermore, because the original data can be rapidly and continuously recorded, the method can rapidly and continuously record the error voltage data at different temperatures at any time, and further process the change of the phase difference at different temperatures, thereby ensuring the reliability and the integrity of the test data. The following detailed description is to be read in connection with the specific embodiments.

In operation S101, a Ka band beacon for transmitting Ka band signals is arranged in a far field region.
In the embodiment of the invention, the general Ka frequency range beacon is kept for 24 hours without stopping, so that enough error voltage data can be recorded.
In operation S102, the Ka antenna is controlled to receive the Ka band signal, and phase calibration is performed on the Ka antenna.
In the embodiment of the invention, before the phase value of the Ka antenna is tested, the initial phase difference between the Ka antenna and the difference channel at the starting moment needs to be ensured to be zero, so that the accuracy of the subsequent test for tracking the phase value change of the Ka antenna is ensured.
In operation S103, the phase-corrected Ka antenna is controlled to track the Ka band beacon, and the Ka antenna is fixed after the Ka antenna deviates from the Ka band beacon by a preset angle.
In the embodiment of the invention, after the initial phase difference calibration of the sum-difference channel is finished, the Ka antenna does not automatically track the Ka frequency range beacon immediately, and after a certain time, the Ka antenna starts to automatically track the Ka frequency range beacon after meeting the self-tracking condition. In the automatic tracking process, when the Ka antenna deviates from the preset angle relative to the Ka frequency band beacon, the Ka antenna is fixed to be stationary, and the deviation from the preset angle may refer to that the azimuth angle of the Ka antenna deviates from the preset angle or the pitch angle deviates from the preset angle, for example, deviates from 0.06 degrees.
In operation S104, the azimuth error voltage and the pitch error voltage corresponding to the Ka antenna are recorded every preset time period.
In the embodiment of the invention, the antenna servo software can be started to automatically record the azimuth error voltage and the pitching error voltage corresponding to the Ka antenna at intervals of a preset time period.
Illustratively, the azimuth error voltage and the pitch error voltage corresponding to the Ka antenna are respectively recorded at a first moment, a preset time interval is reached to a second moment, and the azimuth error voltage and the pitch error voltage corresponding to the Ka antenna are respectively recorded at the second moment. The interval time may be, for example, 1min or 2min, and may be specifically set according to actual requirements, which is not limited in the present invention.
In operation S105, a Ka antenna tracking phase value is determined according to the azimuth error voltage and the elevation error voltage as a function of temperature.
In the embodiment of the present invention, determining the relationship between the Ka antenna tracking phase value and the temperature change according to the azimuth error voltage and the elevation error voltage may include, for example:
and calculating a first difference value between the azimuth error voltage corresponding to the first moment and the azimuth error voltage corresponding to the second moment.
And calculating a second difference value between the pitch error voltage corresponding to the first moment and the pitch error voltage corresponding to the second moment.
And calculating the variation of the tracking phase value of the Ka antenna according to the first difference and the second difference.
And respectively obtaining a first ambient temperature and a second ambient temperature of the Ka antenna at a first moment and a second moment.
And determining the relation of the Ka antenna tracking phase value along with the temperature change according to the variable quantity of the Ka antenna tracking phase value, the first environment temperature and the second environment temperature.
Further, the method may be based on:
