Detailed ways

In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. In addition, although the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in an order different from that here.

In the traditional pattern test method, the horizontal rotation of the turntable is controlled, the rotation angle of the turntable is read in real time, and the power signal received on the receiving device is collected to realize the data collection and drawing of a single pattern. However, in radar antenna measurement, in order to meet the test indicators required by the antenna of the product under test, a large amount of pattern data needs to be collected, so the turntable needs to be rotated back and forth frequently to collect data in real time. In order to ensure the accuracy of the data, the rotation speed of the turntable is limited, resulting in low efficiency in collecting the pattern of the phased array antenna.

In view of this, an embodiment of the present application provides a phased array antenna pattern acquisition method, which is applied to a pattern test system. Please refer to Figure 1, which is a structural schematic diagram of the pattern test system provided in the embodiment of the present application. The pattern test system includes a transmitting end, a receiving end and a PC control end. The various modules of the pattern test system are introduced below.

The transmitting end includes a bracket, a transmitting device and a standard horn antenna. The bracket serves as a support for the horn, and can make the standard horn antenna and the antenna of the product under test on the same horizontal line at the same height. The standard horn antenna serves as a signal transmitting end and plays the role of transmitting signals. The transmitting device serves as the input end of the transmitting signal, and the transmitting device is, for example, a signal source, a vector network analyzer, etc.

The receiving end includes the antenna of the product under test, a turntable and a receiving device. The antenna of the product under test serves as a signal receiving end and can receive the transmitted signal. The antenna of the product under test is a phased array antenna. The turntable can rotate horizontally. The antenna of the product under test is perpendicular to the direction of rotation of the turntable and is fixed on the turntable. The receiving device is connected to the antenna of the product under test and serves as the input end of the received signal. It can display the power of the signal. The receiving device is, for example, a spectrum analyzer, a power meter, a vector network analyzer (also referred to as a vector network analyzer), etc. The PC control end can control the transmitting device, the antenna of the product under test, the receiving device, the turntable and other instruments and equipment through the system program.

The transmitting device and the receiving device may be different types of devices, for example, the transmitting device is a vector network analyzer and the receiving device is a power meter. Alternatively, the transmitting device and the receiving device may be the same type of devices, for example, both the transmitting device and the receiving device are vector network analyzers.

In a possible embodiment, two vector network analyzers may be used, one vector network analyzer as a transmitting device and the other vector network analyzer as a receiving device. In order to simultaneously test multiple directional patterns of the antenna of the product under test, the vector network analyzer has both the function of transmitting and receiving signals. Therefore, in another possible embodiment, one vector network analyzer may be used as both a transmitting device and a receiving device.

As shown in FIG. 2 , it is a schematic flow chart of a phased array antenna pattern acquisition method provided in an embodiment of the present application, and the method can be executed by the PC control terminal in the pattern test system shown in FIG.

S201, controlling the turntable to perform stepping motion according to a preset step length.

In the specific implementation process, the turntable is controlled to start from the initial position and perform stepping motion according to the preset step length by moving the mechanical arm. When the turntable moves to the end position, the turntable completes a preset cycle of stepping motion. The preset step length refers to the distance the turntable moves each time, which can be a fixed value preset by the user or determined according to preset test parameters.

The preset test parameters are parameters set by the user before the test starts. The test parameters include test frequency data, test wave position data, data collection interval, turntable rotation range, turntable rotation speed, and data storage method. Among them, the test frequency data includes multiple test frequencies, the test wave position data includes multiple test wave positions corresponding to each test frequency, the data collection interval is used to indicate the interval for the receiving device to collect data, and the turntable rotation range is used to indicate the starting position and ending position of the turntable rotation.

In a possible embodiment, the preset step length and the preset period are determined according to preset test parameters.

Specifically, the preset period is determined according to the turntable rotation range, that is, the starting position and the ending position of the turntable rotation, and the preset step length is determined according to the data collection interval, the turntable rotation range and the turntable rotation speed, wherein the turntable rotation range is positively correlated with the preset step length, the data collection interval is negatively correlated with the preset step length, and the turntable rotation speed is negatively correlated with the preset step length.

For example, the formula is: preset step length = turntable rotation range/(turntable rotation speed×data collection interval).

S202, after the control turntable completes each stepping motion, obtaining the position data of the turntable.

The position data of the turntable is used to indicate the current position of the turntable, for example, the rotation angle of the turntable from the starting position. After the turntable completes each stepping motion, multiple test frequencies are set in sequence, and multiple test wave positions corresponding to each test frequency are sent to the antenna of the product under test.

S203: Read the test data on the receiving device.

The test data includes power signal data, test frequency data, and test wave position data.

S204: Draw a directional diagram of the antenna of the product under test according to the position data and the test data.

In the specific implementation process, after obtaining the position data of the turntable and the test data on the receiving device, drawing is performed based on the position data and the test data, using the test data on the receiving device as the Y-axis data and the position number of the turntable as the X-axis data, and using the chart control to draw the radiation pattern of the antenna of the product under test and display it on the graphical interface of the system software.

S205, until the turntable completes a preset cycle of stepping motion, and obtains multiple directional diagrams of the antenna of the product under test.

After the turntable completes a stepping motion, it can be determined whether the turntable has completed a preset cycle of stepping motion according to whether the turntable has moved to the end position. Through S201-S204, each time the turntable completes a stepping motion, a radiation pattern of the antenna of the product under test can be obtained. S201-S204 is repeatedly executed until the turntable completes a preset cycle of stepping motion, and multiple radiation patterns of the antenna of the product under test can be obtained.

In a possible embodiment, please continue to refer to FIG. 1 , the antenna of the product under test may further include a combiner, wherein the combined port of the combiner is connected to the first port of the receiving device, and the differential port of the combiner is connected to the second port of the receiving device.

The steps for reading the test data on the receiving device can be divided into three cases, which are introduced below.

Case 1: reading the test data received by the receiving device through the first port.

Case 2: Read the test data received by the receiving device through the second port.

Case 3: reading the test data received by the receiving device through the first port, and reading the test data received by the receiving device through the second port.

For the above three situations, there are three steps to obtain the directional diagram of the antenna of the product under test by drawing according to the position data and the test data, which are introduced below respectively.

For the first case, a combined directivity diagram of the antenna of the product under test is obtained by drawing based on the position data and the test data received by the first port.

For the second case, the position data and the test data received at the second port are plotted to obtain the difference radiation pattern of the antenna of the product under test.

For situation three, the combined radiation pattern of the antenna of the product under test is obtained by drawing according to the position data and the test data received at the first port, and the difference radiation pattern of the antenna of the product under test is obtained by drawing according to the position data and the test data received at the second port.

In the traditional directional pattern test method, only one directional pattern can be collected at one time. In the embodiment of the present application, by connecting the combined port and the differential port of the antenna of the product under test to different ports of the receiving device, the directional patterns of multiple ports can be collected at the same time, which can not only improve the collection efficiency, but also obtain different types of directional patterns (combined directional pattern and differential directional pattern).

In a possible embodiment, the receiving device is a vector network analyzer, and the vector network analyzer is set to a manual trigger mode; before reading the test data on the receiving device, it is also possible to control the vector network analyzer to collect test data in response to the user's manual trigger operation on the vector network analyzer, and record the test data collected by the vector network analyzer at different times in different views.

In a specific implementation process, the vector network analyzer has multiple views. Each manual triggering causes the vector network analyzer to collect the test data received at the current moment and record the test data received at the current moment in the current view.

In a possible embodiment, the steps of collecting data by the vector network analyzer through dual views are as follows:

Switching the view window of the vector network analyzer to a first view, and in response to a manual trigger operation of the vector network analyzer by a user, controlling the vector network analyzer to collect test data at a first moment, and recording the test data at the first moment on the first view;

The view window of the vector network analyzer is switched to a second view, and in response to a manual trigger operation of the vector network analyzer by a user, the vector network analyzer is controlled to collect test data at a second moment, and the test data at the second moment is recorded on the second view.

The process of collecting data through dual views by a vector network analyzer is described in detail below with reference to FIG. 3 .

First, set the receiving device (vector network) to manual trigger mode, set the number of collection points of the receiving device (vector network), that is, the number of times the receiving device (vector network) collects data. Determine whether all test frequencies and all test wave positions corresponding to each test frequency have been sent down. If not, switch the view of the receiving device (vector network) to view 1, manually trigger, and record the currently received power signal data. Then switch the view of the receiving device (vector network) to view 2, manually trigger, and record the currently received power signal data until all test frequencies and all test wave positions corresponding to each test frequency have been sent down, and read all data on the receiving device (vector network).

In a possible embodiment, the step of reading the test data on the receiving device includes:

Determine whether multiple test wave positions corresponding to each test frequency point have been sent down;

If yes, the test data on the receiving device is read.

In the specific implementation process, after the control turntable completes each stepping movement, multiple test frequencies and multiple test wave positions corresponding to each test frequency are sent to the antenna of the product under test. If it is determined that the multiple test wave positions corresponding to each test frequency have been sent, the test data on the receiving device is read. If it is determined that the multiple test wave positions corresponding to each test frequency have not been sent, it is determined whether it is necessary to send a beam instruction to the antenna of the product under test based on the preset test parameters. The beam instruction is used to indicate the wave position of the antenna of the product under test, that is, the beam pointing. If necessary, the beam instruction is sent to the antenna of the product under test to control the test data collected by the receiving device (vector network). If not necessary, the test data collected by the receiving device (vector network) is directly controlled.

In a possible embodiment, before determining whether multiple test wave positions corresponding to multiple test frequency points have been sent, the method further includes:

Determine whether multiple test frequency points have been sent;

If not, set the frequencies of the transmitting and receiving devices.

In the specific implementation process, after the control turntable completes each stepping motion, multiple test frequency points and multiple test wave positions corresponding to each test frequency point are sent down. If it is determined that multiple test frequency points have not been sent down, the frequencies of the transmitting device and the receiving device are cyclically set to multiple test frequency points. If it is determined that multiple test frequency points have been sent down, it is further determined whether the turntable has completed the stepping motion of the preset cycle.

For ease of understanding, the overall process of the phased array antenna pattern acquisition method provided in an embodiment of the present application is described in detail below in conjunction with FIG. 4 .

Before the test begins, connect all the instruments, receiving devices, transmitting devices and communication ports required for the test, and read the control communication protocol of the antenna of the product under test for easy system program control. The user can pre-select the receiving device and transmitting device, and pre-configure test parameters such as test frequency data, test wave position data, turntable rotation range, turntable rotation speed, data collection interval, data storage method, etc.

After the test starts, the system program can obtain various preset test parameters, control the turntable to move to the initial position, and calculate the preset step length according to the preset test parameters. The test parameters include the turntable rotation range, turntable rotation speed, and data collection interval. Then, based on whether the turntable has reached the end position, it is determined whether the turntable has completed a preset cycle of stepping motion. If the turntable has completed a preset cycle of stepping motion, the turntable is controlled to return to the original position, that is, the turntable is controlled to return to the initial position, the collected data is processed, and the data is saved according to the data storage method configured by the user.

Furthermore, if the turntable has not completed a preset cycle of stepping motion, after setting the robotic arm to move to the corresponding point according to the preset step length, determine whether the last frequency point has been sent down. If the last frequency point has been sent down, continue to determine whether the turntable has completed the preset cycle of stepping motion.

If the last frequency point has not been sent down, set the frequency of the transmitting device and the receiving device to determine whether the last beam has been sent down. If the last beam has not been sent down, determine whether to send a beam instruction to the antenna of the product under test according to the preset test parameters. If so, send a beam instruction to control the receiving device to collect data. If not, directly control the receiving device to collect data. If the last beam has been sent down, read the data on the receiving device, use the chart software to draw the directional diagram, and then continue to determine whether the last beam has been sent down.

Taking the traditional pattern test method to test a 180-degree pattern, with a turntable speed of 5°/s as an example, a pattern can be collected in about 30 seconds, and 120 patterns can be collected in about 1 hour. After multiple tests of the system, the phased array antenna pattern collection method provided in the embodiment of the present application can collect more than 600 patterns in 1 hour, and its collection efficiency is 5 times that of the traditional test method.

In summary, the embodiment of the present application provides a method for collecting the radiation pattern of a phased array antenna. By using a system program, the turntable is controlled to perform stepping motion. After each stepping motion of the turntable, the frequency point, wave position, and channel required for the test are issued. After each issuance is completed, the receiving device (vector network) switches the view window up and down, sets the receiving device (vector network) to be manually triggered, and records the data to the receiving device (vector network). Before the next movement of the turntable, all test data on the receiving device (vector network) is read for processing, and the radiation pattern is drawn and displayed on the graphical interface of the system program until the entire motion cycle is completed. The turntable only needs to complete a complete cycle of stepping motion to obtain multiple radiation patterns of multiple frequencies, multiple wave positions, and multiple channels. Its test efficiency is 5 times that of the traditional test method, which can effectively improve the efficiency of radiation pattern acquisition.
