Description

Technical Field

[0001] This invention belongs to the field of electronic jamming technology and relates to a four-sided array reconnaissance jamming transceiver switch matrix. Background Technology

[0002] In the field of electronic countermeasures and radio frequency jamming, a four-sided array reconnaissance and jamming system is a core technical solution for achieving simultaneous omnidirectional and multi-directional reconnaissance and jamming. This system typically requires switching and distributing eight input jamming signals to 32 output channels covering four array faces. At the receiving end, a digital beamformer is needed to form digital beams, enabling flexible selection of specific array element signals and the synthesis of 16 channels within each array face. This transceiver switching matrix, as a crucial hub connecting signal processing and the antenna array, directly impacts the system's jamming effectiveness, size, weight, and engineering cost due to its channel architecture, integration, and reliability.

[0003] Currently, transceiver switch matrices designed for four-sided array reconnaissance and jamming typically separate the receiver and transmitter into independent designs. The receiver employs multi-level, multi-gang switch groups in conjunction with a digital beamformer to achieve signal gating for digital beamforming. Multiple cascaded single-pole double-throw switches complete the combination and gating of the receiving channels. The transmitter uses an 8-input, splitter-4-group independent array channel architecture, distributing the 8 input signals to 4 completely independent RF channels via the splitter. Both the receiver and transmitter use independent switch modules, independent channel interfaces, and independent power and control units, resulting in a distributed layout. Modules are interconnected using conventional threaded RF connectors, making it impossible to integrate the receiving and transmitting functions within a single switch matrix.

[0004] However, because the existing four-sided array reconnaissance and jamming transceiver switch matrix adopts an independent and distributed design for receiving and transmitting, with the receiving end and the transmitting end operating independently, the overall structure of the transceiver switch matrix is ​​loose and has low integration, making it difficult to meet the application requirements of integrated reconnaissance and jamming functions and miniaturized equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a four-sided array-based reconnaissance and jamming transceiver switch matrix, which can reduce the degree of independence and dispersion between receiving and transmitting functions, reduce the looseness of system structure, and improve the integration of transceiver and the efficiency of reconnaissance and jamming coordination.

[0006] To achieve the above objectives, the technical solution provided by the present invention is as follows: A four-sided array-based reconnaissance and jamming transceiver switch matrix includes: The receiver switch module has multiple receiver input channels, which are divided into four arrays. Each array corresponds to a set number of receiver input channels. The receiver switch module is electrically connected to a first control module, which sends array selection control signals to the receiver switch module. The receiver switch module receives multiple receiver input signals from the four arrays through the multiple receiver input channels, and performs array selection (one-to-four) selection on the multiple receiver input signals according to the array selection control signals. The selected signals are then input to a digital beamformer to form a digital beam for reconnaissance.

[0007] At least one transmit switch module is included, which operates independently and in a time-division multiplexing manner with the receive switch module. The transmit switch module has multiple transmit input channels and multiple selectable output channels. The multiple selectable output channels are divided into four arrays, with each array corresponding to a set number of selectable output channels. The multiple transmit input channels are used to receive multiple transmit input signals from external sources. The transmit switch module is electrically connected to a second control module, which sends array gating control signals to the transmit switch module. The transmit switch module includes an array synthesis preprocessing unit and a multiplexing switching chip. The array synthesis preprocessing unit performs phase and amplitude calibration on the multiple transmit input signals before inputting them to the multiplexing switching chip. The multiplexing switching chip switches, amplifies, and filters the calibrated signals and performs array gating on the signals processed by the multiplexing switching chip according to the array gating control signals. The selected signals are output to the antenna for interference.

[0008] The invention is further characterized by: The set number of receiving input channels consists of multiple receiving input channels of different frequency bands. The first control module is also used to send frequency band control signals to the receiving switch module. The frequency band control signals control the receiving switch module to switch between multiple different frequency bands.

[0009] The set number of selectable output channels consists of multiple selectable output channels in different frequency bands.

[0010] The receiving switch module consists of multiple first single-pole quad-throw units, and the transmitting switch module also includes multiple second single-pole quad-throw units. Each first single-pole quad-throw unit and each second single-pole quad-throw unit are composed of three single-pole double-throw RF switch chips connected in cascade and parallel. Each first single-pole quad-throw unit is used to perform array-to-one selection of one of the received input signals according to the array-to-gating control signal sent by the first control module. Each second single-pole quad-throw unit is used to perform array-to-one selection of one of the signals processed by the multiplexing switching chip according to the array-to-gating control signal sent by the second control module.

[0011] The three single-pole double-throw (SPDT) RF switch chips, which are configured in a cascaded and parallel manner, include a first SPDT RF switch chip, a second SPDT RF switch chip, and a third SPDT RF switch chip. The first SPDT RF switch chip and the second SPDT RF switch chip are connected in series, and the second SPDT RF switch chip and the third SPDT RF switch chip are connected in parallel.

[0012] The array synthesis preprocessing unit includes a phase shifter and an adjustable attenuator, which are used to perform phase calibration and amplitude calibration on the multiple transmit input signals, respectively.

[0013] The multiplexing switching chip consists of three dedicated RF chips connected in series. These three dedicated RF chips are used to switch, amplify, and filter the calibrated signal in sequence.

[0014] The bottom of the transmitter switch module has an RF input interface and a power interface, while the side of the transmitter switch module has an RF output interface. Both the RF input interface and the RF output interface are SMP semi-escapement blind mating connectors.

[0015] The array-based four-sided reconnaissance and jamming transceiver switch matrix of the present invention has the following advantages: This invention integrates a receiving switch module and a transmitting switch module within the same matrix. The receiving switch module selects and processes multiple received input signals and inputs them into a digital beamformer to form a digital beam for reconnaissance. The transmitting switch module calibrates, switches, amplifies, and filters external input signals through an array synthesis preprocessing unit and a multiplexed switching chip, then distributes them to multiple selectable output channels and outputs them to the antenna for interference. This invention integrates reconnaissance reception and jamming transmission functions into the same switch matrix, effectively reducing the degree of independence and dispersion between the receiving and transmitting functions, reducing the looseness of the system structure, thereby improving the efficiency of transmission and reception coordination and the integration of equipment. It also makes the overall layout of the switch matrix more compact, meeting the application requirements of integrated reconnaissance and jamming and miniaturization, reducing the complexity of engineering implementation and assembly difficulty, and improving the overall reliability and ease of maintenance of the system.

[0021] like Figure 1As shown, a four-sided array-based reconnaissance and jamming transceiver switch matrix includes a receiving switch module 1 and at least one transmitting switch module 2. The receiving switch module 1 has multiple receiving input channels, divided into four array faces, with each array face corresponding to a set number of receiving input channels. The receiving switch module 1 is electrically connected to a first control module, which sends an array face selection control signal to the receiving switch module 1. The receiving switch module 1 receives multiple receiving input signals from the four array faces through the multiple receiving input channels and performs array face selection (four-to-one) selection on the multiple receiving input signals according to the array face selection control signal. The selected signal is used to input a digital beamformer to form a digital beam for reconnaissance. The transmitting switch module 1 and the receiving switch module 2 operate independently in a time-division multiplexing manner. The transmitting switch module 2 has... The system includes multiple transmit input channels and multiple selectable output channels. The multiple selectable output channels are divided into four array surfaces, with each array surface corresponding to a set number of selectable output channels. The multiple transmit input channels are used to receive multiple transmit input signals from external sources. The transmit switch module 2 is electrically connected to a second control module, which sends array surface gating control signals to the transmit switch module 2. The transmit switch module 2 includes an array synthesis preprocessing unit and a multiplexing switching chip. The array synthesis preprocessing unit performs phase and amplitude calibration on the multiple transmit input signals before inputting them to the multiplexing switching chip. The multiplexing switching chip switches, amplifies, and filters the calibrated signals and performs array surface four-to-one gating on the signals processed by the multiplexing switching chip according to the array surface gating control signals. The selected signals are output to the antenna for interference. This invention integrates a receiving switch module 1 and a transmitting switch module 2 within the same matrix. The receiving switch module 1 performs gating processing on multiple received input signals and inputs them into a digital beamformer to form a digital beam for reconnaissance. The transmitting switch module 2, through an array synthesis preprocessing unit and a multiplexed switching chip, calibrates, switches, amplifies, and filters external input signals before distributing them to multiple selectable output channels and outputting them to the antenna for interference. This invention integrates reconnaissance reception and jamming transmission functions into the same switch matrix, effectively reducing the degree of independence and dispersion between the receiving and transmitting functions, reducing the looseness of the system structure, thereby improving the efficiency of transmission and reception coordination and the integration of equipment. It also makes the overall layout of the switch matrix more compact, meeting the application requirements of integrated reconnaissance and jamming and miniaturization, reducing the complexity of engineering implementation and assembly difficulty, and improving the overall reliability and ease of maintenance of the system.

[0022] like Figure 2As shown, the set number of receiving input channels consists of multiple receiving input channels in different frequency bands. The first control module is also used to send frequency band control signals to the receiving switch module 1. The frequency band control signals control the receiving switch module 1 to switch and select between multiple different frequency bands. It can flexibly select the currently operating receiving frequency band according to reconnaissance needs, realize time-division reconnaissance and gating processing of target signals in different frequency bands, and improve the frequency band adaptability of the receiving module.

[0023] like Figure 2 As shown, the receiving switch module 1 has forty-eight receiving input channels, and each array has a corresponding set number of twelve selectable output channels. The twelve receiving input channels consist of seven first-band receiving input channels and five second-band receiving input channels. The seven first-band receiving input channels consist of two fixed first-band output channels and five band-selectable first-band output channels. The five second-band receiving input channels are five band-selectable second-band output channels. The first control module sends a frequency band control signal to the receiving switch module 1, which controls the receiving switch module 1 to switch between the first and second frequency bands. Using the twelve receiving channels consisting of seven first-band and five second-band channels, including fixed and band-selectable channels, in conjunction with the frequency band control signal sent by the first control module, flexible selection and switching of dual frequency bands at the receiving end can be achieved, adapting to different frequency reconnaissance and interference requirements.

[0024] The frequency band control signal is a one-bit high / low level control signal used to switch between the first and second frequency bands.

[0025] like Figure 3 As shown, the set number of selectable output channels consists of multiple selectable output channels for different frequency bands. This allows for the simultaneous provision of signal output paths for different frequency bands, enabling the simultaneous transmission and distribution of multi-band interference signals, thus improving the frequency band compatibility and signal coverage of the transmitting module.

[0026] like Figure 3As shown, the transmit switch module 2 has eight transmit input channels and thirty-two output channels, with each array corresponding to a set number of eight selectable output channels. There are eleven transmit switch modules 2, totaling eighty-eight transmit input channels and three hundred and fifty-two selectable output channels. The eighty-eight transmit input channels consist of sixty-four first-band transmit input channels and twenty-four second-band transmit input channels. Each transmit switch module 2 is electrically connected to a second control module. Each second control module sends an array selection control signal to the corresponding transmit switch module 2 to control the switching and selection control of the four arrays. By combining eleven transmit switch modules 2, the expansion from eighty-eight inputs (sixty-four first-band and twenty-four second-band) to three hundred and fifty-two selectable outputs is achieved. With the array selection control signal sent by the second control module, the flexible allocation and switching of large-scale omnidirectional interference signals across the four arrays can be realized.

[0027] The first frequency band is preferably 2GHz to 6GHz, and the second frequency band is preferably 8GHz to 12GHz.

[0028] The receiving switch module 1 consists of multiple first single-pole quad-throw (SPQ4) units, and the transmitting switch module 2 includes multiple second SPQ4 units. Each first SPQ4 unit and each second SPQ4 unit is composed of three single-pole double-throw (SPD) RF switch chips connected in a cascaded and parallel configuration. Each first SPQ4 unit performs a 4-to-1 array selection on one of the received input signals according to the receiving array selection control signal sent by the first control module. Each second SPQ4 unit performs a 4-to-1 array selection on one of the signals processed by the multiplexing switching chip according to the array selection control signal sent by the second control module. By using multiple SPQ4 units to construct the receiving switch module 1 and the transmitting switch module 2, with each unit consisting of three cascaded and parallel SPQ4 chips, and cooperating with the first and second control modules to send array selection control signals, independent 4-to-1 array selection can be achieved for multiple received and transmitted signals, improving system integration and channel configuration flexibility.

[0029] Specifically, when the receiving switch module 1 has 48 receiving input channels and each array has 12 selectable output channels, there are 12 first single-pole four-throw units. When the transmitting switch module 2 has 8 transmitting input channels and 32 output channels, there are 8 second single-pole four-throw units. When there are 11 transmitting switch modules 2, with a total of 88 transmitting input channels and 352 selectable output channels, there are 88 second single-pole four-throw units. Each second single-pole four-throw unit is responsible for performing array-to-array four-to-one selection on one of the calibrated signals and outputting it to the selected array.

[0030] The system comprises three single-pole double-throw (SPDT) RF switch chips connected in a cascaded and parallel configuration: a first SPDT RF switch chip, a second SPDT RF switch chip, and a third SPDT RF switch chip. The first SPDT RF switch chip and the second SPDT RF switch chip are connected in series, while the second SPDT RF switch chip and the third SPDT RF switch chip are connected in parallel. This combination of the first SPDT RF switch chip connected in series and the second SPDT RF switch chip and the third SPDT RF switch chip connected in parallel enables the implementation of a single-pole quad-throw (SCT) switch function with a minimum number of chips. The structure is compact and the control logic is simple, which helps to reduce insertion loss and improve switching speed.

[0031] The array synthesis preprocessing unit includes a phase shifter and an adjustable attenuator, which are used to perform phase calibration and amplitude calibration on the multiple transmitted input signals, respectively.

[0032] The multiplexed switching chip consists of three dedicated RF chips connected in series. These three chips sequentially switch, amplify, and filter the calibrated signal. This allows different chips to independently handle the signal switching, amplification, and filtering functions, achieving a high-density integrated layout while ensuring signal processing performance.

[0033] The bottom surface of the transmitter switch module 2 is provided with an RF input interface and a power interface, and the side surface of the transmitter switch module 2 is provided with an RF output interface. Both the RF input interface and the RF output interface are SMP semi-escapement blind mating connectors, preferably JSMP(M)-JHD184-JH, and the RF output interface is preferably JSMP(M)-JHD05-L. This enables rapid blind mating assembly between modules and RF signals, greatly improving assembly efficiency. Moreover, the blind mating structure has anti-vibration and anti-impact characteristics. In a wide temperature range of -40℃ to +60℃, the reliability of signal contact is greatly improved, solving the problem of loosening of traditional connectors.

[0034] The present invention provides a four-sided array reconnaissance jamming transceiver switch matrix, which further includes an assembly base, a receiving switch module 1, a first control module, and each transmitting switch module 2 and each second control module are mounted on the assembly base.

[0035] The present invention provides a four-sided array reconnaissance and jamming transceiver switch matrix, which also includes a power supply and control interface. The power supply and control interface is located on the transmit switch module 2. The power supply and control interface integrates power supply pins for receiving the operating voltage and frequency band control signals and array gating control signals. By using a power supply and control interface that integrates power supply pins and control signal pins, the operating voltage, frequency band control signals and array gating control signals can be connected to the switch module through the same interface, realizing the integrated connection of power supply and control.

[0036] The power supply and control interface uses a J30J-9 connector. The J30J-9 connector integrates the power supply pins and control signal pins into the same connector, enabling integrated access for power supply and control signals.

[0037] The receiver switch module 1 has dimensions of ≤233mm×160mm×25mm. The receiver switch module 1 is fixedly connected to the assembly base by screws. Compared with the traditional distributed design, the volume is reduced, which meets the needs of equipment miniaturization and engineering application.

[0038] The assembly base is a grid-structured metal frame that also serves as a heat dissipation substrate and an electromagnetic shielding layer.

[0039] The invention also includes a power control module, which is connected to the power supply and control interface. It uses a ZhanCheng XC8821 synchronous rectification buck chip to convert the external DC+12V power supply into a -5V negative voltage to power the switching module. The chip can output an average current of 1.4A to meet the power supply requirements of all channels of the switching matrix.

[0040] The SMP semi-escapement blind mating connector is connected to the PCB board using surface mount and soldering reinforcement processes to avoid loosening of the connection due to vibration.

[0041] The top surface of the transmitting switch module 2 is the mounting surface, which is used to fix it to the grid structure of the mounting base; the radio frequency input interface and the power interface are located on the bottom surface of the transmitting switch module 2, and the radio frequency output interface is located on both sides of the switch module.

[0042] The switching matrix operates in both the first and second frequency bands, with a switching time of ≤500ns. It can achieve rapid switching of the four arrays and real-time signal selection of the receiving module, meeting the high-speed real-time jamming requirements of electronic countermeasures systems.

[0043] Among them, the loss of the transmitting end of the transmitting switch module 2 is ≤2dB in the first frequency band and ≤3dB in the second frequency band, the combined channel loss of the receiving module is ≤4.5dB, and the port standing wave ratio of the switching matrix is ​​≤2.0.

[0044] The switching matrix of the present invention operates in two frequency bands: 2GHz~6GHz and 8GHz~12GHz, including a receive mode and a transmit mode, which operate independently in a time-division manner.

[0045] Receive mode: such as Figure 2As shown, a total of 48 received input signals from four array antennas (12 signals per array, including seven 2GHz~6GHz and five 8GHz~12GHz) enter the receiving switch module 1. The first control module sends frequency band control signals and array gating control signals to the receiving switch module 1. The receiving switch module 1 performs dual-band gating control on the input signals according to the frequency band control signals. Each first single-pole quad-throw unit performs array-to-one gating on one of the received input signals according to the array gating control signals and outputs one of the signals. The twelve first single-pole quad-throw units output a total of twelve signals, and input the twelve selected signals into a digital beamformer to form a digital beam, thus completing the reconnaissance and reception processing.

[0046] Transmission mode: Eight externally input transmission signals enter the transmission switch module 2 through the eight transmission input channels. The array synthesis preprocessing unit performs phase and amplitude calibration on the eight transmission input signals and then inputs them to the multiplexing switching chip. The multiplexing switching chip switches, amplifies, and filters the calibrated eight transmission input signals. The second control module sends an array gating control signal to the transmission switch module 2. Each second single-pole four-throw unit performs array gating on one of the calibrated signals according to the array gating control signal and outputs one of the signals. The eight second single-pole four-throw units output a total of eight signals, which are output to the selected array surfaces and finally to the four array antennas to realize the transmission of omnidirectional interference signals.

[0047] Extended configuration: such as Figure 3 As shown, when eleven transmit switch modules 2 are combined, the eighty-eight transmit inputs (sixty-four channels from 2GHz to 6GHz and twenty-four channels from 8GHz to 12GHz) can be expanded to three hundred and fifty-two selectable outputs. The eleven second control modules correspond one-to-one with the eleven transmit switch modules 2. Each second control module sends an array selection control signal to the corresponding transmit switch module 2. The eight second single-pole four-throw units in each transmit switch module 2 select one of the eight calibrated signals from the eight input channels according to the array selection control signal. The eight second single-pole four-throw units output a total of eight signals to the selected array. The eleven transmit switch modules 2 output a total of eighty-eight signals, which are output to the four array antennas respectively, realizing the transmission of omnidirectional interference signals.

[0048] The following are other advantages of the array-based four-sided reconnaissance and jamming transceiver switch matrix of the present invention: First, this invention integrates channel multiplexing, high-density integration of three chips in series, SMP semi-escapement blind mating connectors, and three single-pole double-throw RF switch chips arranged in a cascaded parallel configuration into a four-sided array reconnaissance and interference transceiver switch matrix design, thus achieving integrated structure.

[0049] Secondly, this invention uses a multiplexed switching chip to achieve signal distribution of 64 output channels with eight input channels and groups them into groups of 16 output channels per array face. This achieves the same four-face array coverage function with fewer active channels, reducing the core hardware cost and making it valuable for large-scale engineering applications.

[0050] Third, while reducing system cost and matrix size, this invention replaces traditional multi-level multi-connection switch groups with three single-pole double-throw RF switch chips arranged in cascade and parallel configurations, ensuring low loss and fast switching of RF signals, and possessing wide temperature range adaptability from -40℃ to +60℃, thus improving structural reliability.

[0051] Fourth, by employing SMP semi-escapement blind-mating connectors and grid-shaped mounting units, this invention enables rapid blind-mating assembly, disassembly, and maintenance of switch modules, thereby reducing labor costs in engineering applications.

[0052] Fifth, by using an SMP semi-escapement blind-mating connector as the RF interface and a J30J-9 connector as the power and control interface, this invention has seamless compatibility with existing T components, RF cables and DBF modules without the need for additional modifications.

[0053] Sixth, by reducing the amount of active channels used by more than 60%, the core hardware cost of a single switch matrix is ​​significantly reduced, and the cost advantage will be further expanded after mass production.

[0054] Seventh, by integrating the transmitting switch module and the receiving switch module inside the assembly base, this invention reduces the size of the equipment, lowers transportation, installation and maintenance costs, and improves the engineering adaptability of the equipment, making it widely applicable in fields such as electronic countermeasures, radar and wireless communication.

[0055] Eighth, this invention solves the problems of high cost, large size, low integration and poor reliability of traditional four-sided array reconnaissance and interference switch matrices, and promotes the development of radio frequency switch matrices towards miniaturization, high integration, low cost and high reliability, and has engineering application and promotion value.
