Description

Technical Field

[0001] This invention relates to the field of dynamic integration verification of radio frequency sensors, and specifically to a method, system, device, and medium for efficient integration verification of multiple sensors based on multiple phase centers. Background Technology

[0002] The statements in this section are provided only as background information in connection with this disclosure and may not constitute prior art.

[0003] Information processing technology for flight platforms (such as large aircraft and high-altitude UAV swarms) is a core key to gaining a spatial situational awareness advantage in complex electromagnetic environments. It involves various highly dynamic interactive scenarios, multi-source sensors, and complex electromagnetic games. Modern flight platforms typically utilize multiple types of sensors, including radar, radio frequency reconnaissance, communication, and attribute recognition, and employ information processing technologies such as correlation tracking, trajectory prediction, integrated identification, and sensor management to detect, locate, identify, and track space targets and generate a three-dimensional spatial situational awareness. To address diverse airborne information processing needs, it is necessary to conduct dynamic integration verification of multiple functions operating concurrently under full-scale flight conditions, using multiple sensors, to support system-level simulation and design verification of the flight platform's information processing system.

[0004] However, the radio frequency sensors on flight platforms have wide frequency band coverage, distributed antenna apertures (including directional and omnidirectional antennas), and numerous collaborative functions. For a long time, testing of the entire aircraft's radio frequency system has mainly faced the following technical bottlenecks:

[0005] Firstly, indoor radio frequency injection testing is mainly used for functional connectivity testing. It cannot verify spatial radiation performance, nor can it simulate the spatial electromagnetic environment based on multi-target, highly dynamic interactive scenarios.

[0006] Secondly, field wireless flight testing is easily limited by objective conditions such as weather, site size, and radiation safety, resulting in extremely low testing efficiency and difficulty in reproducing extreme boundary conditions.

[0007] Third, traditional domestic RF simulation anechoic chambers for dynamic integration verification of airborne sensors are limited by physical space and antenna layout technology, and currently only have a fixed "single-phase center". This single-phase center architecture can only test a single RF sensor at a time, which cannot meet the need for simultaneous radiation characteristic verification of multiple sensors in different frequency bands, and therefore cannot verify the collaborative linkage efficiency of multiple sensors such as "passive guidance of active and active guidance of identification".

[0008] Therefore, how to break through the limitations of the physical space of traditional anechoic chambers, construct a dynamic simulation environment with multiple phase centers, and realize the collaborative and efficient integrated verification of multiple frequency bands and multiple sensors of the whole machine is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0009] The purpose of this invention is to address the technical shortcomings of existing technologies, where traditional RF simulation anechoic chambers, due to their single-phase-center capability, cannot simultaneously integrate and verify multiple RF sensors, thus hindering the evaluation of multi-sensor collaborative control and fusion identification performance. The purpose of this invention is to provide a method, system, device, and medium for efficient multi-sensor integration verification based on multiple phase centers.

[0010] The technical solution of the present invention is as follows:

[0011] A multi-sensor efficient integrated verification method based on multiple phase centers includes:

[0012] Step S1: In an anechoic environment, multiple phase centers are constructed in the same airspace based on a multi-band triple spherical array radiating antenna, an array feed control subsystem, and a comprehensive signal source. Multiple six-degree-of-freedom motion tables, controlled synchronously, are used to deploy corresponding test equipment at each of these phase centers. The test equipment includes electronic reconnaissance equipment, radar equipment, and identification and interrogation equipment to ensure the attitude consistency of the test equipment in a unified body coordinate system. The initial positions and motion trajectories of the friendly platform and the opposing platform are set via the system control console, with the opposing platform serving as the target.

[0013] Step S2: The system control console calculates the relative spatial relationship between the tested device and the target in real time, obtains scene parameters and sends them out. The scene parameters include at least relative distance, speed and angle.

[0014] Step S3: The array feed control subsystem modulates the amplitude and phase of the multi-band triple spherical array radiating antenna according to the angle in the scene parameters, and controls the integrated signal source to radiate signals to the electronic reconnaissance equipment at a specified angle;

[0015] Step S4: After the electronic reconnaissance equipment intercepts the signal and obtains the platform angle information, it guides the radar equipment to accurately track the target;

[0016] Step S5: The integrated signal source modulates the time delay, Doppler and space decay characteristics based on the scene parameters to simulate the radar target echo signal, and controls the multi-band triple spherical array radiating antenna to radiate the radar target echo signal to the radar equipment at the corresponding position through the array feed control subsystem;

[0017] Step S6: After the radar device has stably tracked the target, guide the identification and interrogation device to transmit an interrogation signal to the other party platform, and the target antenna set on the other party platform receives the interrogation signal and responds;

[0018] Step S7: Based on the collaborative interaction results of the electronic reconnaissance equipment, the radar equipment, and the identification and interrogation equipment, realize the dynamic integrated verification and fusion identification of multiple sensors with passive guidance and active guidance.

[0019] Furthermore, the multi-band triplet spherical array radiating antenna is arranged in an alternating equilateral triangle pattern within the same spatial domain;

[0020] The spacing between the high-frequency band triplets is configured as 12.5 mrad, the spacing between the mid-frequency band triplets is configured as 25 mrad, and the spacing between the low-frequency band triplets is configured as 50 mrad, in order to ensure the simultaneous radiation of multiple frequency band signals in the same airspace.

[0021] Furthermore, the multiple six-degree-of-freedom motion stages controlled synchronously are respectively deployed with corresponding test devices at the multiple phase centers, including:

[0022] Three devices under test with different frequency bands are simultaneously set up on three six-degree-of-freedom motion tables, so that the antenna aperture center of each device under test is located on the corresponding phase center;

[0023] The motion of the tested equipment is simulated, including its azimuth, pitch, and roll (three angular degrees of freedom) and its X, Y, and Z translational degrees of freedom.

[0024] Furthermore, the system's central control console performs high real-time integrated control based on scenario-driven principles, specifically as follows:

[0025] The system's central control console advances the simulation process in real time according to a preset simulation rhythm to synchronously control each participating device; wherein, the preset simulation rhythm is 1ms.

[0026] Furthermore, the array feed control subsystem modulates the amplitude and phase of the multi-band triplet spherical array radiating antenna according to the angle in the scene parameters, including:

[0027] By selecting and switching the three-element antennas in the multi-band three-element spherical array radiating antenna, a rough position selection of the radiation space can be achieved;

[0028] The high, medium and low frequency band power supply control module in the array power supply control subsystem performs amplitude and phase modulation and signal synthesis of the three branches in the ternary array, thereby realizing the precise position movement of the signal in the ternary array.

[0029] Furthermore, the scene parameters are generated by the simulation scene planning module of the system control console based on the platform configuration, multi-sensor configuration, and motion characteristic simulation of both parties.

[0030] Based on a scenario-driven approach, the system's central control console controls the signal switching time, distance, amplitude, and variation characteristics of the integrated signal source to simultaneously simulate the radiation and scattering characteristics of multiple moving targets in the same airspace, with a maximum of 16 moving targets.

[0031] Furthermore, the multi-sensor dynamic integrated verification and fusion recognition for passive-guided active and active-guided identification includes:

[0032] Based on the detection, interception, target tracking, and interactive response data output by the electronic reconnaissance equipment, the radar equipment, and the identification and interrogation equipment, information fusion identification is performed to generate and output unified situational data reflecting the current state of the entire information system.

[0033] This invention also proposes a multi-sensor high-efficiency integrated verification system based on multiple phase centers to implement the method described above. The system includes:

[0034] The system includes a central control console, multiple six-degree-of-freedom motion tables, a multi-band triple spherical array radiating antenna, an array feed control subsystem, and a comprehensive signal source.

[0035] The plurality of six-degree-of-freedom motion tables are used to mount the device under test; the multi-band triple spherical array radiating antenna is connected to the array feed control subsystem; the system control console is communicatively connected to the plurality of six-degree-of-freedom motion tables, the array feed control subsystem and the integrated signal source for coordinated scheduling.

[0036] The present invention also proposes an electronic device, comprising:

[0037] At least one processor; and a memory in a composite signal source communicatively connected to said at least one processor;

[0038] The memory in the integrated signal source stores instructions that can be executed by the at least one processor. By executing the instructions stored in the memory, the at least one processor performs the method described above.

[0039] The present invention also proposes a computer-readable storage medium for storing instructions that, when executed, cause the method described above to be implemented.

[0040] Compared with existing technologies, the advantages of this invention are:

[0041] 1. Overcoming spatial limitations to achieve concurrent collaborative verification of multiple sensors: This invention constructs multiple non-interfering radio frequency phase centers at the physical level by staggering multi-band (high / medium / low frequency band) triple spherical array radiating antennas in the same spatial domain within an anechoic chamber. Simultaneously, multiple synchronously controlled six-degree-of-freedom motion stages precisely position the distributed antenna apertures of the device under test (DUT) to their corresponding phase centers, simulating various translational and angular motions. This design (technical feature) successfully eliminates collaborative errors caused by differences in anechoic chamber installation positions through physical pose compensation of the six-degree-of-freedom motion stages combined with spatial multiplexing of multi-band antennas (mechanism of action). This ensures the consistency of the DUT's attitude in a unified body coordinate system, solving the pain point of traditional single-phase-center anechoic chambers that can only test "isolated units," and filling the gap in the inability to perform collaborative integrated verification of multiple sensors in an anechoic chamber environment.

[0042] 2. High-precision angle simulation and high-confidence reproduction of complex, highly dynamic scenarios: This invention employs a system control console to advance global control based on a 1ms simulation cycle, combined with a comprehensive signal source to simulate the radiation and scattering characteristics of up to 16 moving targets; and executes a two-level control strategy of "triple antenna switching (coarse adjustment)" and "triple amplitude and phase modulation (fine adjustment)" through an array feeding control subsystem. This design (technical feature) utilizes the microwave beamforming principle to smoothly move the equivalent radiation center (mechanism), realizing accurate angle simulation of multi-phase center radiation signals from multiple RF sensors. It provides a high-concurrency, high-complexity dynamic multi-target extreme testing environment for multi-sensor management algorithms, greatly improving the simulation accuracy and testing efficiency of the integrated verification environment.

[0043] 3. A closed-loop verification system from passive to active operation, highly consistent with real-world, highly dynamic business logic, was constructed: This invention designed a complete interactive verification flow including "electronic reconnaissance signal interception and radar directional tracking (passive guiding active)," "integrated signal source co-location radiation echo," and "radar-guided identification and interrogation (active guidance identification)." This design (technical feature) ensures absolute consistency of target spatial angle (mechanism) by integrating active radiation sources and radar scattering echoes through a unified signal source simulation. This perfectly replicates the underlying data interaction closed loop of the flight platform information system from detection and positioning to identification in an anechoic chamber, providing reliable verification support for generating unified situational data for the entire aircraft information system.

[0050] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0051] Example 1

[0052] Embodiment 1 of this invention provides a high-efficiency multi-sensor integration verification method based on multiple phase centers. Addressing the shortcomings of existing anechoic chambers used in dynamic integration verification of airborne RF sensors, which only have one phase center and cannot simultaneously perform spatial radiation performance and dynamic countermeasures testing on multiple sensors of different frequency bands; and the limitations of traditional RF injection testing, which can only be used for functional connectivity testing (unable to verify dynamic spatial radiation performance based on highly dynamic interactive scenarios), and the susceptibility of field wireless testing to limitations imposed by weather, site size, and radiation safety conditions, this embodiment achieves multi-sensor fusion verification in an anechoic chamber environment through hardware coordination in physical space and time-cycle coordination of control logic. Please refer to... Figures 1-3 Specifically, the method includes the following steps:

[0053] Step S1: In an anechoic environment, multiple phase centers are constructed in the same airspace based on a multi-band triple spherical array radiating antenna, an array feed control subsystem, and a comprehensive signal source. Multiple six-degree-of-freedom motion tables, controlled synchronously, are used to deploy corresponding test equipment at each of the multiple phase centers. The test equipment includes electronic reconnaissance equipment, radar equipment, and identification and interrogation equipment to ensure the attitude consistency of the test equipment in a unified body coordinate system. The initial positions and motion trajectories of the friendly platform and the opposing platform are set through the system's central control console, with the opposing platform serving as the target.

[0054] In this embodiment, to overcome the physical installation limitations of a single-phase-center anechoic chamber, the multi-band triplet spherical array radiating antenna is arranged in an alternating equilateral triangle configuration within the same airspace. Specifically, the spacing between the high-frequency triplets is configured as 12.5 mrad, the spacing between the mid-frequency triplets is configured as 25 mrad, and the spacing between the low-frequency triplets is configured as 50 mrad. This ensures simultaneous radiation of multi-band (high / mid / low-frequency) radio frequency signals within the same airspace without mutual interference.

[0055] Furthermore, the RF sensor antenna apertures on the real aircraft platform are distributed (including directional and omnidirectional antennas). To reproduce this spatial orientation relationship in the anechoic chamber, this embodiment uses three six-degree-of-freedom motion tables to simultaneously mount three test devices (electronic reconnaissance equipment, radar equipment, and identification and interrogation equipment) at different frequency bands. During installation and calibration, the center of the antenna aperture of each test device is strictly positioned on the corresponding high / medium / low frequency band phase center. During the simulation operation phase, the system control console uniformly calculates and synchronously issues drive commands to simulate the motion of the test devices in azimuth, pitch, and roll (three angular degrees of freedom) and X, Y, and Z translational degrees of freedom. Its working principle is that, through the synchronous servoing of multiple six-degree-of-freedom motion tables, multiple dispersed test devices can be forcibly mapped to the same virtual "unified body coordinate system" within the limited space of the microwave anechoic chamber, thereby eliminating the attitude coordination error introduced by the different physical installation positions in the anechoic chamber.

[0056] Step S2: The system control console calculates the relative spatial relationship between the tested device and the target in real time, obtains scene parameters and sends them out. The scene parameters include at least relative distance, speed and angle.

[0057] In this embodiment, the system control console possesses a high real-time integrated control capability based on scenario-driven principles. Under the control of the system synchronization signal, the system control console advances the simulation process in real time according to a preset simulation cycle, thereby controlling each participating device in real time; wherein, the preset simulation cycle is 1ms.

[0058] Furthermore, the scene parameters are generated by the simulation scene planning module of the system control console based on the platform configuration, multi-sensor configuration, and motion characteristics of both interacting parties, to realize a typical complex three-dimensional dynamic interactive scene. Based on a scene-driven approach, the system control console controls the signal on / off time, distance, amplitude, and variation characteristics of the integrated signal source to simultaneously simulate the radiation and scattering characteristics of multiple highly moving targets in the same airspace, with a maximum of 16 moving targets. The injection of a high real-time beat of 1ms and a complex spatial electromagnetic environment with up to 16 targets under high-maneuverability conditions provides high-confidence extreme testing conditions for the multi-sensor dynamic control algorithm.

[0059] Step S3: The array feed control subsystem modulates the amplitude and phase of the multi-band triple spherical array radiating antenna according to the angle in the scene parameters, and controls the integrated signal source to radiate signals to the electronic reconnaissance equipment at a specified angle.

[0060] In this embodiment, the integrated signal source is a radiation / scattering integrated signal source, capable of simulating various complex interactive scenarios and dynamic signals. Accurate angle simulation of the radiation signal at multiple phase centers is crucial for achieving multi-device joint debugging. Specifically, it includes a coarse-to-fine two-level control mechanism:

[0061] First, by selecting and switching the triplet antennas in the multi-band triplet spherical array radiating antenna, a rough location selection of the radiation space is achieved (i.e., the spherical array region where the target is approximately located is selected).

[0062] Subsequently, the high, medium and low frequency band power supply control module in the array power supply control subsystem performs amplitude and phase modulation and signal synthesis of the three branches in the ternary array to achieve precise positional movement of the signal within the ternary array.

[0063] Its underlying signal-level high-precision amplitude and phase modulation mechanism (such as microwave beamforming principle) can smoothly move the equivalent radiation center of the synthesized beam, accurately simulating the dynamic change of the incident angle of a non-cooperative target platform (radiation source target) relative to one's own electronic reconnaissance equipment.

[0064] Step S4: After the electronic reconnaissance equipment intercepts the signal and obtains the platform angle information, it guides the radar equipment to accurately track the target.

[0065] In this embodiment, this step embodies the collaborative control logic of "passive guidance with active control". After the electronic reconnaissance equipment stably intercepts the radiation signal of the opponent platform and calculates the platform's angle information, it sends the angle information as a guidance command to its own radar equipment, enabling the radar equipment to quickly point its beam at the guidance angle for local precise search.

[0066] Step S5: The integrated signal source modulates the time delay, Doppler and spatial attenuation characteristics based on the scene parameters to simulate the radar target echo signal, and controls the multi-band triple spherical array radiating antenna to radiate the radar target echo signal to the radar equipment at the same position through the array feed control subsystem.

[0067] Once the radar equipment is guided to initiate directional tracking, the anechoic chamber environment needs to provide the target echo. Specifically, the integrated radiation / scattering signal source modulates the microwave signal delay based on relative distance, modulates the Doppler frequency shift based on relative velocity, and combines spatial attenuation to modulate the amplitude of the echo signal to simulate the radar target echo signal. In particular, the array feed control subsystem controls the multi-band triple spherical array radiating antenna to radiate the echo signal to the radar equipment under test from the same position. This precise control of the "same position" ensures that the active radiation signal (intercepted by electronic reconnaissance) and the physically scattered echo (intercepted by radar) of the simulated non-cooperative target in the microwave anechoic chamber have strict consistency in spatial angle with each other, thus providing closed-loop support for sensor collaborative verification at the physical level.

[0068] Step S6: After the radar device has stably tracked the target, guide the identification and interrogation device to transmit an interrogation signal to the other party platform, and the target antenna set on the other party platform receives the interrogation signal and responds.

[0069] This step embodies the collaborative workflow of "active guidance and identification." After the radar equipment stably tracks and intercepts the target signal, the guidance and identification interrogation equipment transmits an interrogation stimulus signal to the other platform, supporting the system in determining the target's cooperative or non-cooperative attributes, thus completing the underlying data interaction closed loop for collaborative control and fusion identification.

[0070] Step S7: Based on the collaborative interaction results of the electronic reconnaissance equipment, the radar equipment, and the identification and interrogation equipment, realize the dynamic integrated verification and fusion identification of multiple sensors with passive guidance and active guidance.

[0071] Specifically, the aforementioned integrated verification is based on the detection, interception, target tracking, and interactive response data output by the electronic reconnaissance equipment, the radar equipment, and the identification and interrogation equipment. The system performs fusion identification to ultimately generate and output unified situational awareness data reflecting the current state of the entire system. This embodiment's method is adaptable to more complex dynamic test scenarios, solving the problem that traditional single-phase central anechoic chambers cannot simultaneously perform integrated verification of multiple sensors. It significantly improves the efficiency of multi-RF sensor integrated verification, fills the gap in verifying the collaborative capabilities of multiple sensors across the entire system, and has extremely high application value.

[0072] Example 2

[0073] Based on the same inventive concept as Embodiment 1, Embodiment 2 of the present invention provides a high-efficiency integrated verification system for multiple sensors based on multiple phase centers. This system supports the integrated verification method described in Embodiment 1 in terms of physical architecture and is suitable for testing the collaborative performance of multiple frequency bands and multiple sensors in a microwave anechoic chamber environment.

[0074] Specifically, the system includes: a system control console, multiple six-degree-of-freedom motion stages, a multi-band triplet spherical array radiating antenna, an array feeding control subsystem, and a comprehensive signal source.

[0075] Regarding hardware topology connections and functional allocation:

[0076] The multiple six-degree-of-freedom motion tables, housed in a microwave anechoic chamber, are used to respectively mount the test equipment (i.e., electronic reconnaissance equipment, radar equipment, and identification and interrogation equipment) in the corresponding frequency bands. During system operation, the six-degree-of-freedom motion tables are controlled to perform actions, simulating the azimuth, pitch, and roll (three angular degrees of freedom) and X, Y, and Z (three translational degrees of freedom) of the test equipment. This eliminates physical discrepancies in the installation positions of different devices, ensuring the consistency of the test equipment's attitude within a unified body coordinate system.

[0077] The multi-band triplet spherical array radiating antenna is deployed in the same airspace in front of the device under test and is connected to the array feed control subsystem via radio frequency cables. The spherical array radiating antenna has an alternating equilateral triangle layout, with a high-frequency triplet spacing of 12.5 mrad, a mid-frequency triplet spacing of 25 mrad, and a low-frequency triplet spacing of 50 mrad. This forms multiple physical phase centers in the same airspace, ensuring that multiple radio frequency signals in the high, mid, and low frequency bands can simultaneously radiate to the device under test without interference.

[0078] The integrated signal source is a radiation / scattering integrated signal source, and its radio frequency output is connected to the input of the array feed control subsystem. The integrated signal source has the ability to simulate various complex combat scenarios and dynamic signals of various moving targets. It is used to generate electromagnetic wave signals (including active radiation signals and radar target echo signals) containing time delay, Doppler frequency shift and spatial attenuation characteristics based on preset platform parameters, relative distance, velocity and other characteristics of the two interacting parties.

[0079] The array feed control subsystem is located between the synthesized signal source and the spherical array radiating antenna. Internally, it includes high, medium, and low frequency band feed control modules, primarily responsible for the selection and switching of the triplet antenna, amplitude and phase modulation of the three branches within the triplet, and signal synthesis. This enables precise positional movement of the radio frequency signal within the triplet (i.e., high-precision angle simulation), and feeds the synthesized signal into the corresponding spherical array radiating antenna for radiation to the device under test.

[0080] The system's central control console, serving as the "brain" and scheduling hub of the entire integrated verification system, communicates with the multiple six-degree-of-freedom motion stages, the array power supply control subsystem, and the integrated signal source via Ethernet or a dedicated control bus for coordinated scheduling. The central control console possesses high real-time integrated control capabilities based on scenario-driven principles, incorporating modules for simulation scenario planning, test operation control, and real-time simulation calculation. It advances the simulation process in real-time according to a 1ms simulation cycle, calculates the relative spatial relationship between the tested equipment and the target in real-time, and issues drive commands to each subsystem, thereby completing multi-device dynamic closed-loop verification of "passive guidance to active, and active guidance to identification."
