Description

Technical Field

[0001] The present invention relates to the technical field of phased array anti-interference, and in particular to a receiving phased array anti-interference channel correction method, system and storable medium. Background Art

[0002] Phased array radar or communication systems process signals received by multiple receiving channels to achieve high-precision signal measurement and transmission. However, in actual operation, due to non-ideal characteristics such as device manufacturing process, temperature change, aging, data clock domain conversion, and environmental factors, there are delays, phases, and amplitude differences between the receiving channels. Each receiving channel has amplitude fluctuations and phase nonlinearity within the band, which must be corrected before normal operation to ensure system performance.

[0003] The calibration of the receiving channel is usually performed in an environment without external interference using a specific calibration signal. However, when there are interference signals in the working environment, especially when there are strong in-band interference signals, traditional calibration methods often have difficulty distinguishing between calibration signals and interference signals, resulting in reduced calibration accuracy or even failure of the calibration process, which affects the performance of the entire system to varying degrees. In a complex electromagnetic environment, how to effectively resist external interference and ensure the accuracy of the calibration process is one of the main challenges facing current technology.

[0004] Although some existing solutions attempt to suppress interference through various signal processing technologies, such as some methods suppress interference based on the time domain, frequency domain, and spatial domain characteristics of the interference signal, and some methods suppress interference through signal modulation such as spread spectrum and pulse compression or coherent accumulation, these methods mainly suppress interference after the system enters normal working state, and lack effective solutions specifically for the problem that the receiving channel is susceptible to interference during the correction process. In addition, some processing methods are time-consuming and resource-intensive and cannot meet real-time processing requirements.

[0005] If the calibration process is not accurate enough, it will not only cause system performance degradation, but also affect the effectiveness of other interference suppression measures running under normal system conditions. Therefore, it is necessary to develop a method that can accurately complete the calibration of the receiving channel in an environment with external interference to improve the robustness and anti-interference performance of the phased array system. Summary of the invention

[0006] In order to solve the technical problems existing in the background technology, the present invention proposes a receiving phased array anti-interference channel correction method, system and storable medium.

[0032] Figure 2 The present invention provides a schematic structural diagram of an implementation of a receiving phased array anti-interference channel correction system. DETAILED DESCRIPTION

[0033] like Figure 1 and 2 As shown, Figure 1 The figure is a flow chart of an implementation of a method for correcting anti-interference channels of a receiving phased array proposed by the present invention. Figure 2 The present invention provides a schematic structural diagram of an implementation of a receiving phased array anti-interference channel correction system.

[0034] The present invention provides a method for correcting an anti-interference channel of a receiving phased array, comprising the following steps:

[0035] S1. Initial external calibration stage:

[0036] The adjustable amplifier in the phased array receiving channel is set to a high gain state, the adjustable amplifier in the correction channel is set to a low gain state, the external correction analog switch is closed, and the internal correction analog switch is opened;

[0037] The external correction signal a generated by the correction signal generating module passes through the correction channel and the external correction analog switch to output an external radio frequency correction signal b, and the external radio frequency correction signal b is radiated outward through the external correction antenna probe, received by the phased array antenna element, and fed into the corresponding receiving channel for filtering, amplification, digitization and other pre-processing to obtain the initial high-gain external correction data c of the receiving channel;

[0038] Among them, the external RF correction signal b is fed into the receiving channel through the phased array antenna element in a direct connection manner.

[0039] S2, initial internal calibration stage:

[0040] The adjustable amplifier in the phased array receiving channel is set to a low gain state, the adjustable amplifier in the correction channel is set to a high gain state, the external correction analog switch is opened, and the internal correction analog switch is closed;

[0041] The initial internal correction signal d generated by the correction signal generating module passes through the correction channel and the internal correction analog switch, and then outputs the initial internal radio frequency correction signal e, which is then fed into each phased array receiving channel through the internal correction coupling network for preprocessing, and then the initial low-gain internal correction data f of each receiving channel is obtained;

[0042] Among them, the internal radio frequency correction signal e is fed into the receiving channel through the internal correction coupling network in a spatial coupling manner.

[0043] In a specific setting, the gain value of the adjustable amplifier in the phased array receiving channel in S2 is less than the initial value of the adjustable amplifier in the phased array receiving channel in S1; the gain value of the adjustable amplifier in the correction channel in S2 is greater than the initial value of the adjustable amplifier in the correction channel in S1. The above two change differences can be the same. The stronger the anti-interference ability required by the system, the greater the adjustment range of the gain value.

[0044] In addition, in S1, the time difference between the moment when the external correction signal a is generated and the moment when the high gain external correction data c of each receiving channel is obtained is T1; in S2, the time difference between the moment when the internal correction signal d is generated and the moment when the low gain internal correction data f of each receiving channel is obtained is T2; T1=T2.

[0045] S3, power-on internal calibration stage: repeat the steps of S2 to obtain power-on low-gain internal calibration data h;

[0046] S4. Calculate the correction coefficient j of each receiving channel according to the initial high-gain external correction data c, the initial low-gain internal correction data f and the power-on low-gain internal correction data h of each receiving channel, and compensate each receiving channel.

[0047] Specifically, the following steps are included:

[0048] Calculate the ratio of the initial high-gain external correction data c to the low-gain internal correction data f of each receiving channel to obtain the internal and external correction difference data g of each receiving channel;

[0049] The power-on low-gain internal correction data h is correspondingly multiplied with the internal and external correction difference data g to obtain the channel correction data i of each receiving channel;

[0050] The correction coefficient j of each receiving channel is calculated according to the channel correction data i.

[0051] In this embodiment, the proposed receiving phased array anti-interference channel correction method, system and storable medium, by performing low-gain internal correction in the system correction stage, and correspondingly performing low-gain internal correction when the system is turned on, significantly improves the anti-interference ability of the system receiving correction process, so that the system can accurately complete the receiving channel correction when there is external interference in the environment, especially strong in-band interference, thereby improving the stability and reliability of the system in a complex electromagnetic environment. At the same time, the present invention does not need to change the architecture and complexity of the system hardware and algorithm, and the system has strong versatility.

[0052] In the specific calibration process, S1 and S2 can be completed in a darkroom before leaving the factory. At this time, in S2, after obtaining the initial low-gain internal correction data f of each receiving channel, the ratio of the initial high-gain external correction data c of each receiving channel to the low-gain internal correction data f is calculated to obtain the internal and external correction difference data g of each receiving channel.

[0053] The adjustable amplifier gains in the receiving channel and the correction channel in S1 and S2 are generally set to a variety of combination values. Before leaving the factory, S1 and S2 are repeated for each gain combination to obtain the internal and external correction error data g of each receiving channel corresponding to the gain combination; after leaving the factory, one of the gain combinations and the corresponding internal and external correction error data g are selected according to application requirements to complete S3 and S4.

[0054] Accordingly, S3 is performed each time the power is turned on. At this time, in S4, the correction coefficient j of each receiving channel is calculated according to the initial high gain external correction data c, the initial low gain internal correction data f and the power-on low gain internal correction data h of each receiving channel, which specifically includes the following steps:

[0055] The power-on low-gain internal correction data h is correspondingly multiplied with the internal and external correction difference data g to obtain the channel correction data i of each receiving channel;

[0056] The correction coefficient j of each receiving channel is calculated according to the channel correction data i.

[0057] During specific operation, when the system is switched from the pre-shipment high-gain external calibration stage to the pre-shipment low-gain internal calibration stage, the system cannot be powered off and shut down.

[0058] In actual operation, the gain value of the adjustable amplifier in the phased array receiving channel in the normal working state may be set to be the same as the gain value of the adjustable amplifier in the phased array receiving channel in S1.

[0059] This embodiment also provides a phased array system, including: a receiving channel, a correction channel, a correction signal generating module, an external correction analog switch, an internal correction analog switch, an external correction antenna probe, an internal correction coupling network, a phased array antenna element and a host;

[0060] The host is used to control one or more of the receiving channel, the correction channel, the correction signal generating module, the external correction analog switch, the internal correction analog switch, the external correction antenna probe, the internal correction coupling network, and the phased array antenna element to implement the above-mentioned receiving phased array anti-interference channel correction method.

[0061] This embodiment further provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and the computer program is executed by a processor to implement the operating steps of the receiving phased array anti-interference channel correction method as described above.

[0062] The receiving phased array anti-interference channel correction method of this embodiment is described in detail below through specific examples.

[0063] See also Figure 1 and Figure 2 , the specific implementation process of realizing the anti-interference channel correction of the receiving phased array is as follows:

[0064] S101: The system enters the high-gain external calibration stage before shipment, sets the adjustable amplifier in the phased array receiving channel to a high-gain state, sets the adjustable amplifier in the calibration channel to a low-gain state, closes the external calibration analog switch, and opens the internal calibration analog switch.

[0065] Specifically, during the high-gain external calibration phase before shipment, the system should be placed in a darkroom environment without obvious external interference.

[0066] In the embodiment of the present invention, the adjustable amplifier gain in the phased array receiving channel can be set to 60 dB, and the adjustable amplifier gain in the correction channel can be set to 20 dB.

[0067] S102: The correction signal generating module generates an external correction signal a, and outputs a radio frequency correction signal b through the correction channel and the external correction analog switch. The radio frequency correction signal b is radiated outward through the external correction antenna probe, received by the phased array antenna element, and fed into the corresponding receiving channel; the receiving channel filters, amplifies and digitally pre-processes the radio frequency correction signal b, and then samples to obtain high-gain external correction data c of the receiving channel.

[0068] Specifically, the external correction antenna probe can be moved in sequence to the same distance in front of each phased array antenna element, and the correction signal generating module generates an external correction signal a each time; the correction channel performs digital-to-analog conversion, up-conversion, filtering and amplification on the external correction signal a, and then outputs a radio frequency correction signal b through an external correction analog switch; the radio frequency correction signal b is radiated outward through the external correction antenna probe, received by the opposite phased array antenna element, and directly fed into the corresponding receiving channel; the receiving channel filters, amplifies, down-converts and performs analog-to-digital conversion on the radio frequency correction signal b, and then samples to obtain high-gain external correction data c of the receiving channel.

[0069] Exemplarily, the receiving phased array system in this embodiment may be a narrowband system, and the external correction signal a may be a complex frequency signal:

[0070] S a (n) = e jωn ,in,

[0071] S a (n) is the complex frequency correction signal a; ω is the digital angular frequency, and ω=2πfn / f s , f is the simulation frequency, f s is the sampling rate, n is an integer between [0, N), and N is the number of sampling points of the signal.

[0072] In this embodiment, the analog frequency of the complex frequency signal a is f=1 MHz, and the sampling rate is f s =2.5Msps, N=1000.

[0073] Exemplarily, the high-gain external correction data c of the receiving channel may be:

[0074] in,

[0075] A c and The external correction link and the receiving channel perform amplitude modulation and phase modulation on the external correction signal a respectively, wherein the phase modulation includes the link additional phase and the link delay equivalent phase of the narrowband system.

[0076] S103: The system enters the low-gain internal calibration stage before delivery, sets the adjustable amplifier in the phased array receiving channel to a low-gain state, sets the adjustable amplifier in the calibration channel to a high-gain state, disconnects the external calibration analog switch, and closes the internal calibration analog switch.

[0077] Specifically, when the system switches from the pre-shipment high-gain external calibration stage to the pre-shipment low-gain internal calibration stage, it should be ensured that the system is powered off without interruption. The reduction in the adjustable amplifier gain value in the phased array receiving channel in step S103 relative to the initial value in step S101 is the same as the increase in the adjustable amplifier gain value in the calibration channel relative to the initial value in step S101. The stronger the anti-interference capability required by the system, the greater the adjustment range of the gain value.

[0078] In the embodiment of the present invention, the adjustable amplifier gain in the phased array receiving channel can be set to 0 dB, and the adjustable amplifier gain in the correction channel can be set to 80 dB, which can provide 60 dB of anti-interference suppression capability.

[0079] S104: The correction signal generating module generates an internal correction signal d, and outputs a radio frequency correction signal e through a correction channel and an internal correction analog switch. The radio frequency correction signal e is fed into each phased array receiving channel through an internal correction coupling network.

[0080] Specifically, the internal correction signal d is the same as the external correction signal a in step S102, and is a complex frequency signal with the same frequency and initial phase; the correction channel performs digital-to-analog conversion, up-conversion, filtering and amplification on the internal correction signal d, and then outputs the RF correction signal e through the internal correction analog switch; the RF correction signal e is sent to the coupler corresponding to each receiving channel through the internal correction coupling network, and is fed into each phased array receiving channel through spatial coupling.

[0081] S105: Each receiving channel filters, amplifies and digitally preprocesses the radio frequency correction signal e, and then samples to obtain low-gain internal correction data f of each receiving channel.

[0082] Specifically, the receiving channel filters, amplifies, down-converts and performs analog-to-digital conversion on the radio frequency correction signal e, and then samples to obtain low-gain internal correction data f of each receiving channel.

[0083] Exemplarily, the low-gain internal correction data f of the receiving channel may be:

[0084] in,

[0085] A f and The internal correction link and the receiving channel perform amplitude modulation and phase modulation on the correction signal respectively.

[0086] S106: Calculate the ratio of the high-gain external correction data c to the low-gain internal correction data f of each receiving channel to obtain the internal and external correction error data g of each receiving channel.

[0087] Exemplarily, the internal and external correction error data g can be

[0088] S107: After leaving the factory, each time the system is turned on, it enters the low-gain internal calibration stage, repeats steps 3, 4, and 5, and obtains the low-gain internal calibration data h of each receiving channel at this startup.

[0089] Exemplarily, the low-gain internal correction data h of the receiving channel at this startup may be:

[0090] in,

[0091] A h and The internal correction link and the receiving channel perform amplitude modulation and phase modulation on the correction signal respectively.

[0092] S108: Multiply the low-gain internal correction data h of this startup with the internal and external correction error data g correspondingly to obtain the channel correction data i of each receiving channel.

[0093] Exemplarily, the channel correction data i of the receiving channel may be

[0094]

[0095] S109: Calculate the correction coefficient j of each receiving channel according to the channel correction data i, and compensate each receiving channel; reset the adjustable amplifier in the phased array receiving channel to a high gain state, and the system enters the normal working stage after leaving the factory.

[0096] Specifically, the correction coefficient j can be obtained by calculating the ratio of the channel correction data i to the correction data a (or d), and then the correction coefficient j is compensated to each receiving channel through the correction compensation module. After the correction compensation, the adjustable amplifiers in the phased array receiving channel and the correction channel are reset to the gain values ​​during the external calibration, and the system enters the normal working stage after leaving the factory.

[0097] Exemplarily, the correction factor j can be

[0098] In the embodiment of the present invention, after calibration and compensation, the adjustable amplifier gains in the phased array receiving channel and the calibration channel are set to 60 dB and 20 dB respectively, and then the system enters the normal working stage after leaving the factory.
