The selection of the data bit is mainly realized by a Combo Box control to select the serial data bit number by pulling down. The baud rate setting is also realized by a Combo Box control to select the serial baud rate by pulling down. The selection of the stop bit is also realized by a Combo Box control to select the stop bit number by pulling down. The selection of the check bit is also realized by a Combo Box control to select the check bit mode by pulling down. Each Combo Box can be manually inputted to facilitate the expansion of the serial port. The opening and closing of the serial port is mainly realized by a Command control. A green circle and a red circle picture are inserted in front of the control. The two pictures completely overlap. When the serial port is opened, the green picture is displayed on the upper layer. When the serial port is closed, the red circle picture is displayed on the upper layer. The opening and closing of the serial port can be visualized.

Counter zero is mainly to reset the Label control in the receiving area, and receiving area empty is mainly to clear the RichText Box control in the receiving area.

[0080] c) Serial port return receiving area

[0081] The serial port return receiving area is composed of a Rich Text Box, which is used to display the real-time received string of the computer serial port.

[0082] d) Send area settings

[0083] Send area settings are mainly for displaying the number of received strings, selecting whether to display the received area data in hexadecimal, and implementing counter zero, receiving area empty, and single code sending.

[0084] The number of transmissions is mainly implemented by a Label control to display the number of transmitted data. Hexadecimal display is mainly implemented by a Check control to output hexadecimal data to the serial port when selected. Counter zero, receiving area empty, and single code sending are mainly implemented by Command controls. Counter zero is mainly to reset the Label control in the sending area, sending area empty is mainly to clear the RichText Box control in the sending area, and single code sending is mainly to output the string in the RichText Box control of the serial port sending area to the serial port.

[0087] 2) Send Excel correction code value file

[0088] The sending Excel correction code value file is mainly realized by opening Excel and EXCEL sending two Command controls, a RichTextBox control and a Label control. The TEXT Box control mainly fills the range of the EXCEL file that needs to send the correction code value (for example, the TEXT Box control fills A1:Q36, which means that the code value in the entire region from A1 to Q36 in the EXCEL file needs to be sent. According to A1 to A36 as the first command sending, B1 to B36 as the second command sending, and so on until Q1 to Q36 as the last command sending). The Label control is mainly used to record the number of command lines in the EXCEL file (for example, if the TEXT Box control fills A1:Q36, the Label control will record from 1 to 36). The opening Excel Command control mainly selects the position of the Excel file that needs to be sent, and the EXCEL sending mainly sends the correction code value to the phased array antenna according to the region in the RichTextBox control one by one.

[0089] 3. Phased array antenna index debugging layer

[0090] The phased array antenna index debugging layer is used for debugging various types of indexes of the data link phased array antenna, including data link phased array antenna type selection, power control, antenna wave position control, antenna real-time state inquiry, electronic tag debugging, power step test, temperature monitoring, power attenuation debugging, frequency hopping interval debugging, continuous self-check inquiry, beam establishment time debugging, and frequency switching time debugging.

This area is mainly composed of eight Option controls, each of which represents an antenna project ICD protocol. For example, when the x2xD data link antenna Option control is selected, it means that the power control, antenna wave position control, antenna real-time state inquiry, electronic tag debugging, power control debugging, attenuation debugging, etc. during the debugging process all use the x2xD data link antenna data link antenna ICD protocol for communication.

[0093] 2) Power control

For example, start transceiving 1:1 is mainly to make the antenna switch according to the time ratio of receiving and transmitting 50%, stop transceiving 1:1 is to make the antenna product stop 1:1 mode and return to receiving state; start transceiving 5:1 is to make the antenna product switch according to the time ratio of receiving 83% and transmitting 17%, stop transceiving 5:1 is to make the antenna product close 5:1 mode and return to receiving state; TR power off is to make the product TR large current power off, and the antenna only guarantees power supply for wave controller and AIU, TR power on is to restore the power supply for TR; power on is mainly for the process of inputting no current to the antenna to power all modules; receiving is to control the antenna product in full receiving mode, transmitting is to control the antenna product in full transmitting mode; standby is to control the antenna product in standby mode, only the wave controller is powered on, and the rest are all powered off; closing is to require shutdown.

[0095] 3) Antenna wave position control

[0096] Antenna wave position control is mainly to realize the control of data link antenna product single tone signal, mainly using four Option controls, four Text Box controls and two Command controls. Two Option controls are mainly to select wideband and narrowband of antenna single tone signal. Two Option controls realize continuous output and stop continuous output selection, four TextBox controls mainly set the frequency, azimuth, elevation and power control of the antenna. Two Command controls mainly realize single output and continuous output of wave position control code value.

[0097] Antenna wave position control depends on whether the test antenna needs to select wideband or narrowband mode, whether it needs to continuously output the same wave position, for example, a data link antenna needs to select wideband mode, frequency is set to 0, elevation is 0, power control is 0, after setting, click the output button, the antenna product will shift according to the wave position design, and the corresponding indicators will be displayed in the vector network analyzer or spectrum analyzer.

[0100] Two pictures (overlapping green and red circle pictures) and a Label control are mainly used for visualizing whether the functions of state reporting, self-checking, BIT, work log, electronic tag, channel calibration and exit calibration are normal. If all the functions are normal, the green circle picture is on the top, the red circle picture is on the bottom, and the Label control displays that the state reporting, self-checking, BIT, work log, electronic tag, channel calibration and exit calibration are normal. If all the functions are abnormal, the red circle picture is on the top, the green circle picture is on the bottom, and the Label control displays that the state reporting, self-checking, BIT, work log, electronic tag, channel calibration and exit calibration are abnormal. Seven Command controls are mainly used for inquiring seven real-time states of state reporting, self-checking, BIT, work log, electronic tag, channel calibration and exit calibration. A real-time state analysis area mainly consists of a List Box control, which is mainly used for displaying the self-checking analysis, BIT analysis and electronic tag analysis of the antenna product implementation backhaul.

The electronic tag debugging is mainly realized by fifteen Text Box controls and a Command control. The first seven of the fifteen Text Box controls represent the antenna product number, which is set according to the numbering rule (year-batch-number), wherein the number can be up to 999, and the remaining eight Text Box controls represent the production date, which is set according to the regulation (year, month, day). The Command control is mainly used for inputting the product number and production date into the antenna product according to the ICD protocol of each data link antenna, and finally the electronic number information of the product can be verified through the electronic tag Command control in the antenna real-time state inquiry. The electronic tag debugging process is as shown in Figure 8 .

[0103] 6) Power step test

[0104] Power step test is mainly to test whether the product power control meets the requirements, it is the precondition of debugging power attenuation, power step test can use vector network analyzer or use spectrum analyzer to complete the test work.

The power step test process is shown in Figure 9 .

[0105] 7) Temperature monitoring

[0106] Temperature monitoring is mainly realized by a Check Box control and two Text Box controls, wherein the Check Box control is mainly used to start the temperature monitoring command, one Text Box control is mainly used to fill in the temperature monitoring data return period, and one Text Box control is used to display the internal temperature of the antenna product. The temperature monitoring process is shown in Figure 10 .

[0107] 8) Power attenuation debugging

[0108] Power attenuation debugging mainly needs to complete the debugging of transmit and receive preset attenuation. It is mainly realized by ten Text Box controls and two Command controls, ten Text Box controls, five of which are preset transmit attenuation, and five of which are preset receive attenuation. Two Command controls, one for attenuation query, and one for preset attenuation.

[0109] First, power attenuation debugging must be completed by power step test, according to the compensation code value calculated from the test results, the transmit and receive preset attenuation can be preset and screened in the frequency band.

[0110] Secondly, temperature compensation mainly combines the temperature compensation characteristics of the device to carry out temperature power attenuation debugging, so temperature screening debugging must be carried out before attenuation query, and the information of temperature compensation can be determined after completing attenuation query.

[0111] Finally, the power attenuation debugging work is completed through the preset attenuation button.

[0112] The first, second and third Text Box controls in the transmit preset attenuation and receive preset attenuation area mainly debug the attenuation values needed to be preset for each frequency band, and the fourth and fifth Text Box controls mainly implement the temperature compensation values of the antenna product transmit preset attenuation. The power attenuation debugging process is shown in Figure 11 .

[0114] The frequency hopping interval debugging realizes the frequency hopping test function of the antenna product according to a preset step frequency (for example, 5 MHz) as one step, which is mainly realized by two Option controls, two Text Box controls and one Command control. First, the test can still be tested by using a vector network analyzer or a spectrum analyzer, the two Option controls are mainly used to select the instrument used for testing as a vector network analyzer or a spectrum analyzer, the two Text Box controls are mainly used to set the test frequency band, one sets the start frequency and the other sets the end frequency, and finally the frequency hopping interval test Command control is clicked. The antenna wave position control will test from the start frequency as the first point every preset step frequency (for example, 5 MHz) as the next frequency point, and record the test frequency point value and power value, after the test is completed, the intervals of all tests are calculated in the way of the previous one minus the next one, and the average value of all intervals is obtained. The final test result is obtained, and whether the test result meets the requirements is compared, if it meets the requirements, it is not processed, if it does not meet the requirements, the correction code is calculated, the phased array antenna is input, and the test is performed again until the index meets the requirements.

When the Check Box control is triggered, the inquiry is started, and when the Check Box control is not triggered, the inquiry is stopped. The continuous self-check inquiry process is shown in Figure 13 .

[0117] 11) Beam establishment time debugging

[0118] The beamforming time setting is primarily used for debugging the beamforming time of phased array antenna products. The debugging area is mainly implemented using three Text Box controls and one Command control. One Text Box is used to set the antenna's operating frequency, and the other two are used to set the antenna's azimuth and elevation angles. The default test setting is 0 degrees for both azimuth and elevation. The Command control is set as the beamforming Command control to trigger the start button for beamforming time debugging. Once triggered, it sends a beamforming time value at frequency F2, azimuth 0 degrees, and elevation 0 degrees to the phased array antenna. After the test, the result is compared with the specifications. If the specifications are met, debugging exits. If not, a compensation value is automatically calculated based on the test value and applied to the antenna product. The test is repeated after compensation until the specifications are met. The beamforming time debugging process is as follows: Figure 14 As shown.

[0119] 12) Frequency switching time adjustment

[0120] The frequency switching time is mainly used to debug the frequency switching time of phased array antenna products. The default azimuth and elevation angles are 0 degrees. The time from the start of operation at the initial frequency to the start of operation at the final frequency is called the frequency switching time. Debugging is mainly implemented using two Text Box controls and one Command control. The two Text Box controls are used to set the start and end frequencies. The switching time Command control is used to trigger the frequency switching time test. After completing the instrument connection, the waveforms at the start frequency F0, azimuth 0 degrees, and elevation 0 degrees are sent to the phased array antenna product. After obtaining the level value in the vector network analyzer, the waveforms at the end frequency F3, azimuth 0 degrees, and elevation 0 degrees are sent to the phased array antenna product. After obtaining a stable level value in the vector network analyzer, the time is recorded and compared with the specifications. If the specifications are met, the test ends; otherwise, the compensation code value is calculated according to the tested specifications, automatically input into the phased array antenna, and the test is repeated until the specifications are met. The frequency switching time debugging process is as follows: Figure 15 As shown.

[0121] 4. Multi-beam automatic test control and data storage layer

[0122] The multi-beam automatic test control and data storage layer is primarily designed to perform simultaneous multi-beam testing of data link antenna patterns, axial ratio patterns, pointing accuracy, and other performance indicators, thereby improving testing efficiency. This layer mainly performs data testing and is divided into three parts: test content selection, beam download, and test area.

[0123] 1) Test content selection

[0124] The test content selection is mainly to realize the test index selection, which is realized by eight Check Box controls. Two Check Box controls are used to select the receiving and transmitting, and the other four Check Box controls are used to select the test items such as the test and the pattern, the difference pattern, the axial ratio pattern and the pointing accuracy.

[0125] 2) Beam download

[0126] The beam download is mainly to realize the code value related to the frequency, the azimuth and the elevation to be tested to be downloaded to the analog terminal controller. When the turntable rotates to the pulse signal, the beam outputs according to the code value existing in the analog terminal controller in advance. The output can realize the multi-beam pattern test.

[0127] The area is composed of five Text Box controls, three List Box controls and ten Command controls. The three Text Box controls, the three List Box controls and the nine Command controls (add Command control, remove Command control and clear Command control) cooperate to complete the list setting of the frequency, the azimuth angle and the elevation angle. A pulse delay setting Text Box control is used to set the pulse delay, an already transmitted beam number Text Box control is used to record the number of transmitted beams, and the last beam download Command control is used to trigger the beam download.

[0128] For example, a certain data link antenna needs to be tested at four frequency points F0, F1, F2 and F3, two slopes at 0° and 180°, eight beams at 0°, 10°, 20°, 30°, 40°, 50°, 60° and 70°, and 64 and patterns need to be tested. According to the frequency F0, the azimuth 0°, the elevation 0°, 10°, 20°, 30°, 40°, 50°, 60° and 70°, the frequency F0, the azimuth 180°, the elevation 0°, 10°, 20°, 30°, 40°, 50°, 60° and 70°, the frequency F1, the azimuth 0°, the elevation 0°, 10°, 20°, 30°, 40°, 50°, 60° and 70°, the frequency F1, the azimuth 180°, the elevation 0°, 10°, 20°, 30°, 40°, 50°, 60° and 70°, the cycle mode is completed until 56 beams are downloaded.

[0129] 3) Test area

[0130] The test area mainly realizes the multi-beam pattern test function, and is mainly realized by a ProgressBar progress bar control and a Command control. The ProgressBar progress bar control is mainly used for real-time display of the test progress, and the start test Command control is mainly used for triggering a test instruction. After the test is completed, the test data is stored as an EXCEL file.

[0131] The multi-beam automatic test control and data storage layer processing flow is as shown in Figure 16

[0132] In addition, the multi-beam automatic test control and data storage layer is also used for recording the use of the debugging system, and mainly realizes that when the debugging system is opened, a txt document named with the date of the day is established. The document records all operations on the debugging system on the day, such as receiving and sending, starting to receive and send 1:1, power control test, and the like. As long as all operations on the debugging system are recorded.

[0133] Preferably, the configuration requirements of the data link phased array antenna debugging system on the running environment are as shown in Figure 17
