Description

Technical Field

[0001] This invention relates to the field of signal testing, and more specifically, to a testing method, apparatus, equipment, and medium for a broadband radio frequency receiving system. Background Technology

[0002] As a core component of modern communications, a broadband radio frequency (RF) receiving system can convert received RF signals into intermediate frequency (IF) signals suitable for subsequent digital processing over a wide frequency range. Direction finding, a crucial function of a broadband RF receiving system, enables the location of unknown or known RF signal sources, necessitating testing of this capability.

[0003] In testing solutions for the direction-finding function of broadband RF receiving systems, it is typically necessary to construct a complex test environment based on a microwave anechoic chamber, which requires prolonged use of the resource-constrained chamber for testing. Therefore, these solutions suffer from low testing efficiency and long testing time commitments. Summary of the Invention

[0004] The present invention aims to provide a test method, apparatus, equipment and medium for a broadband radio frequency receiving system, in order to solve the problems of low test efficiency and long test resource occupation time in related schemes for direction finding function testing.

[0005] In a first aspect, this application provides a test method for a broadband radio frequency receiving system, comprising: The radio frequency signal transmitted by the microwave signal source is divided into at least one sub-radio frequency signal by a preset power divider network. The amplitude of at least one sub-RF signal is adjusted by a preset attenuation network to obtain at least one adjusted sub-RF signal; wherein the adjusted at least one sub-RF signal meets the amplitude difference requirement of each direction-finding antenna in the broadband RF receiving system. Based on at least one adjusted sub-radio frequency signal, target orientation information is determined; wherein, target orientation information is used to indicate the spatial data of the microwave signal source sensed by the broadband radio frequency receiving system. Based on the preset azimuth information and the target azimuth information, a target test result is generated; the target test result is used to indicate whether the direction finding function of the broadband radio frequency receiving system is normal, and the preset azimuth information is used to indicate the actual spatial data of the microwave signal source.

[0006] The technical solution provided in this application offers at least the following advantages: After dividing the radio frequency signal transmitted by the microwave signal source into at least one sub-radio frequency signal through a preset power divider network, the amplitude of the at least one sub-radio frequency signal is adjusted through a preset attenuation network to obtain at least one adjusted sub-radio frequency signal. Based on the adjusted at least one sub-radio frequency signal, target azimuth information for indicative of the broadband radio frequency receiving system's perception of spatial data from the microwave signal source is determined. Based on the preset azimuth information and target azimuth information for indicative of the microwave signal source's actual spatial data, a target test result for indicative of whether the direction-finding function of the broadband radio frequency receiving system is functioning correctly is generated. Thus, by combining the power divider network and the attenuation network, this application generates adjusted sub-radio frequency signals to simulate real signals, enabling the broadband radio frequency receiving system to directly test the direction-finding function based on the adjusted sub-radio frequency signals. This reduces reliance on a microwave anechoic chamber, simplifies the testing environment, reduces the time spent occupying microwave anechoic chamber resources, and improves testing efficiency.

[0007] One possible implementation further includes, before amplitude adjustment of at least one sub-RF signal via a preset attenuation network: Obtain the antenna pattern of the broadband radio frequency receiving system; wherein, the antenna pattern is used to indicate the distribution of the radiation characteristics of each direction-finding antenna in various directions in space; Based on the antenna pattern, an amplitude value recording table is generated; the amplitude value recording table is used to indicate the amplitude value and amplitude difference of each direction-finding antenna in the corresponding test azimuth.

[0008] Another possible implementation is that the attenuation network includes at least one attenuator and a pass-through, each attenuator and pass-through corresponding to a different sub-RF signal; the attenuator is used to reduce the strength of the sub-RF signal, and the pass-through is used to relay and amplify the strength of the sub-RF signal; Amplitude adjustment of at least one sub-radio frequency signal is performed using a preset attenuation network, including: Based on the amplitude value recording table, the adjustment weights corresponding to each attenuator and straightener are determined; where each attenuator and straightener corresponds to a different direction-finding antenna, the adjustment weights are used to compensate for the signals received by the direction-finding antennas. Based on the adjustment weights corresponding to each attenuator and pass-through, the sub-RF signals corresponding to each attenuator and pass-through are adjusted to obtain at least one adjusted sub-RF signal, so that the at least one adjusted sub-RF signal simulates the real signal.

[0009] Another possible implementation involves determining the adjustment weights for each attenuator based on an amplitude value recording table, including: Based on the azimuth and antenna name of the direction-finding antenna corresponding to the attenuator and the straightener, obtain the corresponding amplitude difference value from the amplitude value record table; Adjustment weights are generated based on the corresponding magnitude differences.

[0010] Another possible implementation involves generating target test results based on preset azimuth information and the target azimuth information, including: Detect whether the preset orientation information is the same as the target orientation information; In response to the fact that the preset azimuth information and the target azimuth information are the same, an azimuth test result is generated to indicate that the test of each direction-finding antenna is normal at the current test azimuth based on the current test frequency, and the azimuth test result is recorded; wherein, the test frequency is used to indicate the test parameters set by the microwave signal source; In response to the difference between the preset azimuth information and the target azimuth information, an azimuth test result is generated to indicate the test abnormality of each direction-finding antenna at the current test frequency, and the azimuth test result is recorded. Based on the azimuth test results corresponding to all test azimuths at the current test frequency, the target test result is generated.

[0011] Another possible implementation is to generate the target test result based on the azimuth test results corresponding to all test azimuths at the current test frequency, including: In response to obtaining the azimuth test results corresponding to all test azimuths of the current test frequency, obtain the azimuth test results corresponding to all test azimuths of the next test frequency and record the corresponding azimuth test results. In response to obtaining the azimuth test results for all test azimuths corresponding to all test frequency points, the target test result is generated based on all the azimuth test results.

[0012] Another possible implementation involves generating target test results based on all orientation test results, including: If all azimuth test results indicate that the test is normal, a target test result is generated to indicate that the direction finding function of the broadband radio frequency receiving system is normal; otherwise, a target test result is generated to indicate that the direction finding function of the broadband radio frequency receiving system is abnormal.

[0013] Secondly, this application provides a test apparatus for a broadband radio frequency receiving system, comprising: The acquisition module is used to divide the radio frequency signal transmitted by the microwave signal source into at least one sub-radio frequency signal through a preset power divider network; The acquisition module is also used to adjust the amplitude of at least one sub-radio signal through a preset attenuation network to obtain at least one adjusted sub-radio signal; wherein the at least one adjusted sub-radio signal meets the amplitude difference requirement of each direction-finding antenna in the broadband radio frequency receiving system. The processing module is used to determine the target azimuth information based on at least one adjusted sub-radio frequency signal; wherein the target azimuth information is used to indicate the spatial data of the microwave signal source sensed by the broadband radio frequency receiving system. The processing module is also used to generate target test results based on preset azimuth information and target azimuth information; wherein, the target test results are used to indicate whether the direction finding function of the broadband radio frequency receiving system is normal, and the preset azimuth information is used to indicate the real spatial data of the microwave signal source.

Detailed Implementation

[0018] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0019] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0020] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0021] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0022] During the commissioning, testing, and maintenance phases of a broadband radio frequency receiving system, the relevant testing solutions typically require the construction of a complex test environment based on a microwave anechoic chamber. The direction-finding function of the broadband radio frequency receiving system is then tested within this environment to determine its status.

[0023] The complex testing environment based on a microwave anechoic chamber typically includes instruments and equipment for signal indication (such as microwave signal sources, indicating antennas, cables, etc.). These instruments and equipment are mounted on a special fixture at a certain distance from the broadband radio frequency equipment system under test. The broadband radio frequency receiving system under test is mounted on a special fixture in the microwave anechoic chamber. The instruments and equipment for signal indication emit radio frequency signals into the external space through the indicating antenna as target indication signals. The broadband radio frequency equipment judges whether the direction finding function meets the requirements by comparing the received parameters of the spatial signals.

[0024] However, testing solutions for the direction-finding function of broadband RF receiving systems typically require the construction of a complex test environment based on a microwave anechoic chamber. This necessitates setting up instruments, the device under test (DUT), a power-on environment, and testing cables, resulting in lengthy testing times and low efficiency. Furthermore, the long-term occupation of scarce resources such as microwave anechoic chambers hinders mass production, system debugging, testing, and maintenance. Therefore, solutions for direction-finding function testing suffer from low testing efficiency and long testing resource consumption periods.

[0025] To address the aforementioned technical problems, this application provides a testing method, apparatus, device, and medium for a broadband radio frequency (RF) receiving system. The method involves dividing the RF signal transmitted from a microwave signal source into at least one sub-RF signal using a pre-defined power divider network. Then, the amplitude of each sub-RF signal is adjusted using a pre-defined attenuation network to obtain an adjusted sub-RF signal. Based on this adjusted sub-RF signal, target azimuth information is determined to indicate the broadband RF receiving system's perception of spatial data from the microwave signal source. Based on the pre-defined azimuth information and the target azimuth information, which indicate the actual spatial data of the microwave signal source, a target test result is generated to indicate whether the direction-finding function of the broadband RF receiving system is functioning correctly. Thus, by combining the power divider network and the attenuation network, this application generates adjusted sub-RF signals to simulate real signals, enabling the broadband RF receiving system to directly test its direction-finding function based on these adjusted sub-RF signals. This reduces reliance on a microwave anechoic chamber, simplifies the testing environment, reduces the time spent occupying microwave anechoic chamber resources, and improves testing efficiency.

[0026] The embodiments provided in this application will now be described in detail with reference to the accompanying drawings.

[0027] Figure 1 This is a schematic diagram of a hardware framework provided for an embodiment of this application. The test method for a broadband radio frequency receiving system provided in this application can be applied to… Figure 1 In the hardware framework shown. For example... Figure 1 As shown, the hardware framework includes a microwave signal source 101, a power divider network 102, an attenuation network 103, a broadband radio frequency receiving system under test 104, and a control device 105.

[0028] The control device 105 is communicatively connected to the microwave signal source 101, the power divider network 102, the attenuation network 103, and the broadband radio frequency receiving system under test 104. The microwave signal source 101 is connected to the power divider network 102 via a radio frequency cable, and the attenuation network 103 is connected to the power divider network 102 and the broadband radio frequency receiving system under test 104 via radio frequency signals.

[0029] In some embodiments, the microwave signal source 101 outputs a radio frequency signal that meets preset signal characteristics and power values ​​based on the control of the control device 105.

[0030] In some embodiments, the power divider network 102 includes a plurality of 1-to-n power dividers. The power dividers in the power divider network 102 realize the splitting of the output radio frequency signal of the microwave signal source 101, that is, the function of 1 input and n outputs, and meet the amplitude consistency requirements of the power split radio frequency path.

[0031] In some embodiments, the attenuation network 103 includes at least one numerically controlled attenuator and a pass-through, wherein the attenuator reduces the output signal amplitude, and the pass-through increases the output signal amplitude, thereby adjusting the amplitude of each radio frequency signal, and each attenuator and pass-through meets the amplitude consistency requirement. Under the control of the control device 105, a weighted attenuation function for the radio frequency signal is implemented, thereby simulating the fixed amplitude difference information of the real signal.

[0032] In some embodiments, the broadband radio frequency receiving system 104 under test includes a direction finding processor and multiple direction finding antennas, wherein each attenuator and pass-through corresponds to a different direction finding antenna. The direction finding processor determines the target azimuth information for instructing the broadband radio frequency receiving system to sense spatial data of the microwave signal source based on the radio frequency signals received through each direction finding antenna, and then sends the target azimuth information to the control device 105.

[0033] In some embodiments, after receiving the target azimuth information, the control device 105 generates a target test result to indicate whether the direction finding function of the broadband radio frequency receiving system is normal, based on the preset azimuth information used to indicate the real spatial data of the microwave signal source and the target azimuth information.

[0034] The control device 105 can be a device with wireless / wired transceiver capabilities, such as a mobile phone, computer, wearable device, in-vehicle device, augmented reality (AR) / virtual reality (VR) device, laptop computer, ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), etc. This application embodiment does not limit the specific device form of the control device 105. Figure 1 The example shown is a computer, with control device 105 as an example.

[0035] The hardware framework described in this application is for the purpose of more clearly illustrating the technical solutions of this application, and does not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will know, with the emergence of new hardware, the technical solutions provided in this application are also applicable to similar technical problems.

[0036] The testing method for the broadband radio frequency receiving system provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0037] Figure 2 This is a flowchart illustrating a test method for a broadband radio frequency receiving system provided in an embodiment of this application. This test method for the broadband radio frequency receiving system can be applied to the control device 105. Figure 3 This is a schematic diagram of an antenna array radiation pattern test provided in an embodiment of this application. (Combined with...) Figure 2 and Figure 3 The following describes the test method for the broadband radio frequency receiving system provided in the embodiments of this application: S201. The radio frequency signal transmitted by the microwave signal source is divided into at least one sub-radio frequency signal through a preset power divider network.

[0038] As an example, by using at least one power divider in a power divider network, the power of the radio frequency signal transmitted by the microwave signal source at the current test frequency is split, thereby realizing the 1-input-n-output function of the power divider to obtain at least one sub-radio frequency signal, and the amplitude of each sub-radio frequency signal is the same.

[0039] Among them, the test frequency is used to indicate the test parameters of the microwave signal source, such as signal characteristics and power value, as well as the current location parameters of the microwave signal source.

[0040] In one possible implementation, after obtaining at least one sub-RF signal, before adjusting the amplitude of at least one sub-RF signal through a preset attenuation network, or before dividing the RF signal transmitted by the microwave signal source into at least one sub-RF signal through a preset power divider network, the antenna pattern of the broadband RF receiving system is obtained.

[0041] like Figure 3 As shown, the antenna radiation pattern is obtained according to the actual radiation pattern test system. The radiation pattern test system is set up in a microwave anechoic chamber and obtains the antenna radiation pattern by connecting the antenna mounting bracket and each direction-finding antenna in the broadband radio frequency receiving system through radio frequency cables. The distance between the antenna mounting bracket and each direction-finding antenna meets the test requirements. The antenna radiation pattern is used to indicate the distribution of the radiation characteristics of each direction-finding antenna in the broadband radio frequency receiving system in various directions in space.

[0042] In one possible implementation, an amplitude value recording table is generated based on the antenna pattern. This table indicates the amplitude value and amplitude difference of each direction-finding antenna at the corresponding test azimuth. The amplitude value recording table is shown in Table 1 below: Table 1

[0043] The same target orientation is used to indicate the current test orientation of each direction-finding antenna based on the current test frequency. The test frequency is used to indicate the test parameters of the current microwave signal source, such as signal characteristics and power value, as well as the location parameters of the current microwave signal source.

[0044] S202. The amplitude of at least one sub-radio frequency signal is adjusted by a preset attenuation network to obtain at least one adjusted sub-radio frequency signal.

[0045] The attenuation network includes at least one attenuator and a cut-through, with each attenuator and cut-through corresponding to a different sub-RF signal.

[0046] For example, based on the amplitude value recording table, the adjustment weights corresponding to each attenuator and straightener are determined, wherein each attenuator and straightener corresponds to a different direction-finding antenna, and the adjustment weights are used to compensate for the signals received by the direction-finding antennas.

[0047] In one possible implementation, the corresponding amplitude difference is obtained from the amplitude value record table based on the azimuth and antenna name of the direction-finding antenna corresponding to the attenuator and the straightener, and adjustment weights are generated based on the corresponding amplitude difference.

[0048] For example, based on the adjustment weights corresponding to each attenuator and pass-through, the sub-RF signals corresponding to each attenuator and pass-through are adjusted to obtain at least one adjusted sub-RF signal, so that the at least one adjusted sub-RF signal simulates the real signal.

[0049] S203. Determine the target azimuth information based on at least one adjusted sub-radio frequency signal.

[0050] As an example, after the broadband radio frequency receiving system obtains at least one adjusted sub-radio frequency signal through each direction-finding antenna, the direction-finding processor in the broadband radio frequency receiving system determines the target azimuth information based on the adjusted at least one sub-radio frequency signal. The target azimuth information is used to indicate the spatial data of the broadband radio frequency receiving system's perception of the current microwave signal source.

[0051] S204. Based on the preset orientation information and the target orientation information, generate the target test results.

[0052] Among them, the target test result is used to indicate whether the direction finding function of the broadband radio frequency receiving system is normal, and the preset azimuth information is used to indicate the actual spatial data of the microwave signal source.

[0053] As an example, it checks whether the preset orientation information is the same as the target orientation information.

[0054] In one possible implementation, in response to the fact that the preset azimuth information is the same as the target azimuth information, an azimuth test result is generated to indicate that the test of each direction-finding antenna is normal at the current test azimuth based on the current test frequency, and the azimuth test result is recorded and saved.

[0055] In one possible implementation, in response to the difference between preset azimuth information and target azimuth information, an azimuth test result is generated to indicate an anomaly in the current test azimuth of each direction-finding antenna based on the current test frequency, and the azimuth test result is recorded and saved.

[0056] As an example, the target test result is generated based on the azimuth test results corresponding to all test azimuths at the current test frequency.

[0057] In one possible implementation, in response to obtaining the azimuth test results corresponding to all test azimuths of the current test frequency, the azimuth test results corresponding to all test azimuths of the next test frequency are obtained and the corresponding azimuth test results are recorded.

[0058] In response to obtaining the azimuth test results corresponding to all test azimuths of the current test frequency, that is, determining whether the current test azimuth of the current test frequency is the last test azimuth, if so, it is determined that all test azimuths of the current test frequency are completed, and the test of all test azimuths of the next test frequency is performed; if not, the azimuth test results corresponding to the next test azimuth are obtained until the azimuth test results corresponding to the last test azimuth are obtained.

[0059] In one possible implementation, in response to obtaining the azimuth test results for all test azimuths corresponding to all test frequency points, a target test result is generated based on all the azimuth test results.

[0060] In response to obtaining the azimuth test results for all test azimuths corresponding to all test frequency points, that is, determining whether the current test frequency point is the last test frequency point, if so, determining that the test of all test azimuths corresponding to all test frequency points is completed and the corresponding test results are obtained; if not, continuing to test all test azimuths for the next test frequency point until the azimuth test results for all test azimuths corresponding to the last test frequency point are obtained.

[0061] In one possible implementation, in response to all orientation test results indicating normal testing, a target test result is generated to indicate that the orientation finding function of the broadband radio frequency receiving system is normal; otherwise, a target test result is generated to indicate that the orientation finding function of the broadband radio frequency receiving system is abnormal.

[0062] In one possible implementation, after generating a corresponding test report based on all the orientation test results and saving the test report locally for the testers to review, the broadband radio frequency receiving system is powered off.

[0063] The testing method for a broadband radio frequency (RF) receiving system provided in this application divides the RF signal transmitted by a microwave signal source into at least one sub-RF signal using a preset power divider network. Then, it adjusts the amplitude of the at least one sub-RF signal using a preset attenuation network to obtain an adjusted at least one sub-RF signal. Based on the adjusted sub-RF signal, target azimuth information is determined to indicate the broadband RF receiving system's perception of spatial data from the microwave signal source. Based on the preset azimuth information and the target azimuth information, which indicate the actual spatial data of the microwave signal source, a target test result is generated to indicate whether the direction-finding function of the broadband RF receiving system is normal. Thus, by combining the power divider network and the attenuation network, this application generates adjusted sub-RF signals to simulate real signals, enabling the broadband RF receiving system to directly test its direction-finding function based on the adjusted sub-RF signals. This reduces reliance on a microwave anechoic chamber, effectively shortens the system debugging, testing, and maintenance cycle, greatly improves testing efficiency, and reduces the time spent occupying microwave anechoic chamber resources.

[0064] In some embodiments, this application also provides a testing apparatus for a broadband radio frequency receiving system.

[0066] The acquisition module 401 is used to divide the radio frequency signal transmitted by the microwave signal source into at least one sub-radio frequency signal through a preset power divider network.

[0067] The acquisition module 401 is also used to adjust the amplitude of at least one sub-radio frequency signal through a preset attenuation network to obtain at least one adjusted sub-radio frequency signal; wherein the at least one adjusted sub-radio frequency signal meets the amplitude difference requirement of each direction-finding antenna in the broadband radio frequency receiving system.

[0068] The processing module 402 is used to determine the target orientation information based on at least one adjusted sub-radio frequency signal; wherein the target orientation information is used to indicate the spatial data of the microwave signal source sensed by the broadband radio frequency receiving system.

[0069] The processing module 402 is also used to generate target test results based on preset azimuth information and target azimuth information; wherein, the target test results are used to indicate whether the direction finding function of the broadband radio frequency receiving system is normal, and the preset azimuth information is used to indicate the real spatial data of the microwave signal source.

[0070] In some embodiments, the acquisition module 401 is specifically used to acquire the antenna pattern of the broadband radio frequency receiving system before the amplitude of at least one sub-radio frequency signal is adjusted by a preset attenuation network; wherein the antenna pattern is used to indicate the distribution of the radiation characteristics of each direction-finding antenna in various directions in space; and an amplitude value recording table is generated based on the antenna pattern; wherein the amplitude value recording table is used to indicate the amplitude value and amplitude difference of each direction-finding antenna in the corresponding test azimuth.

[0071] In some embodiments, the acquisition module 401 is specifically used to determine the adjustment weights corresponding to each attenuator and pass-through in the attenuation network based on the amplitude value record table; wherein each attenuator and pass-through corresponds to a different direction-finding antenna, and the adjustment weights are used to compensate for the signals received by the direction-finding antennas. Based on the adjustment weights corresponding to each attenuator and pass-through, the sub-RF signals corresponding to each attenuator and pass-through are adjusted to obtain at least one adjusted sub-RF signal, so that the at least one adjusted sub-RF signal simulates the real signal.

[0072] In some embodiments, the acquisition module 401 is specifically used to acquire the corresponding amplitude difference from the amplitude value record table according to the azimuth and antenna name of the direction-finding antennas corresponding to the attenuator and the straightener; and generate adjustment weights based on the corresponding amplitude difference.

[0073] In some embodiments, the processing module 402 is specifically used to detect whether the preset orientation information is the same as the target orientation information; In response to the fact that the preset azimuth information is the same as the target azimuth information, an azimuth test result is generated to indicate that the test of each direction-finding antenna is normal at the current test azimuth based on the current test frequency, and the azimuth test result is recorded; wherein, the test frequency is used to indicate the test parameters set by the microwave signal source; In response to the difference between the preset azimuth information and the target azimuth information, an azimuth test result is generated to indicate an abnormality in the current test azimuth of each of the direction-finding antennas based on the current test frequency, and the azimuth test result is recorded. Based on the azimuth test results corresponding to all test azimuths at the current test frequency, the target test result is generated.

[0074] In some embodiments, the processing module 402 is specifically used to obtain the azimuth test results corresponding to all test azimuths of the current test frequency point, obtain the azimuth test results corresponding to all test azimuths of the next test frequency point, and record the corresponding azimuth test results in response to obtaining the azimuth test results corresponding to all test azimuths of the current test frequency point. In response to obtaining the azimuth test results for all test azimuths corresponding to all test frequency points, the target test result is generated based on all the azimuth test results.

[0075] In some embodiments, the processing module 402 is specifically configured to generate a target test result indicating that the direction finding function of the broadband radio frequency receiving system is normal in response to all azimuth test results indicating that the test is normal; otherwise, it generates a target test result indicating that the direction finding function of the broadband radio frequency receiving system is abnormal.
