[0051] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in this specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0052] It should be further understood that the term "and / or" used in this specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0053] Please refer to Figure 1 the specific embodiments shown. The present invention discloses an airborne anti-stealth early warning radar and its digital simulation test method for the combat environment, including the following steps:

[0054] S1. Construct a combat situation environment and set up a simulation scenario;

[0055] Among them, in step S1, it includes: constructing a platform, editing the platform flight route, newly building a radar equipment, newly building a jamming equipment, and clutter setting.

[0056] Specifically, as Figure 2As shown in the figure, it consists of 3 computing workstations, a gigabit network switch, etc. Each computing workstation realizes interconnection and distributed information synchronization and interaction through a high-speed gigabit network, and each computing workstation is equipped with a dedicated software. The first workstation is installed with a combat scenario target general control software, which is used for combat situation scenario editing, three-dimensional situation calculation, simulation control, and simulation database access. It can set the combat scenario, target characteristics, clutter environment, and interference environment through the combat situation scenario. The display content includes the combat situation tree, three-dimensional situation, interference signal waveform, etc.; the second workstation is equipped with a dedicated GPU (graphics processing unit) and installed with a radar information processing software. Radar scheduling, signal generation, signal processing, and data processing are all completed within the GPU, reducing the real-time and bandwidth requirements of network transmission. The display content is the intermediate process data of radar signal processing; the third workstation is installed with a radar target display control software, which is used for radar working mode switching, captured target display, action distance evaluation, and error analysis. The display content includes the radar PPI, two-dimensional situation, radar signal, target list, etc.

[0057] Specifically, as Figure 3 shown, the combat scenario target general control subsystem mainly consists of combat situation scenario, simulation control, situation calculation and display, and database.

[0058] The combat situation scenario is used to complete the construction of the combat platforms, weapons and equipment, and combat environment of both sides of the anti-stealth early warning radar confrontation, mainly including the combat situation management and combat situation editing modules. Combat situation management includes operations such as creating, opening, modifying, closing, and deleting combat situations. Combat situation editing is to perform addition and deletion operations on combat platforms, target platforms, radars, and interference equipment for the current combat situation, and can edit and revise platform parameters and equipment parameters. The clutter configuration tool can be used to add or delete ground clutter and sea clutter in the combat scenario, and set or modify parameters such as clutter type, clutter level, and backscattering coefficient in each enclosed area. When constructing or editing a combat situation, the configuration of platform parameters, equipment parameters, and environmental parameters can be realized by calling the database, and the assumed combat situation can be stored in the database.

[0059] The simulation control is based on the simulation time axis to complete the dynamic deduction and calculation of the early warning radar combat scenario. It provides simulation settings, simulation control, simulation drive, and middle-layer services. Simulation settings refer to the setting of deduction parameters such as simulation duration and step; simulation control completes services such as combat situation loading, simulation process management, synchronization management, information interaction between simulation subsystems or modules, and start, pause, continue, and end of simulation deduction; simulation drive supports time trigger, event trigger, human-in-the-loop drive, and scheduling according to established strategies; the middle-layer service is a middle-layer component that provides services to all views and is used for M (data model) V (view) separation.

[0060] Situation calculation and display mainly include spatio-temporal relationship calculation and 3D situation display modules. The spatio-temporal relationship calculation module is used to calculate the spatial relationships among the early warning aircraft radar, target platforms, and jammers at each simulation beat. The 3D situation display is based on a digital map and displays combat situation information such as the geographical environment, target distribution, and movement tracks of target platforms.

[0061] The database is a common resource library that provides basic models and data for the development and operation of the early warning radar simulation system software. It mainly includes a combat situation scenario library, equipment parameter library, 3D model library, platform track library, target characteristic library, geographical information library, etc.

[0062] S2, deploy combat situation parameters, and execute the simulation according to the simulation parameters to obtain simulation data information;

[0063] Specifically, as Figure 4 shown, the radar information processing subsystem is the core of the simulation system. It uses signal-level simulation to simulate the working, control, and processing processes of the early warning aircraft radar, and provides electromagnetic models and signal models for the dynamic interaction between targets and the environment. Early warning radar simulation includes antenna, resource scheduling, signal generation, signal processing, and data processing; the interaction models include interference models, clutter models, target characteristic models, electromagnetic propagation models, etc.

[0064] The early warning aircraft radar simulation runs according to the radar control beat and obtains information such as interference, clutter, target echoes, and movement parameters from other models according to the radar detection interaction requirements. The early warning radar adopts different working modes and signal processing algorithms for different combat targets such as air, sea, and over-the-horizon. The signal processing algorithms of the early warning radar mainly include space-time two-dimensional processing algorithms, time-domain accumulation processing algorithms, and over-the-horizon processing algorithms. To meet the needs of teaching and scientific research, the original echo signals and intermediate process data of radar signal processing and data processing are displayed.

[0065] The interference model is used to simulate the interference signals encountered by the early warning radar. The interference methods include support side-lobe interference and self-defense main-lobe interference, and the signal patterns include noise suppression interference and multi-false target interference.

[0066] The clutter model is used to generate refined sea clutter random signals, providing environmental background echoes for the signals received by the airborne early warning radar, and being able to support the research and testing of clutter suppression algorithms.

[0067] The target characteristic model can not only independently calculate the target RCS statistical model according to the set parameters, but also query more refined RCS data from the target simulation library.

[0068] The electromagnetic propagation model is used for calculations such as the multipath effect and propagation attenuation of electromagnetic waves between the transceiver links of electronic devices.

[0069] Specifically, asFigure 5 As shown in the figure, the radar target display control subsystem includes radar operating mode control, target list display, PPI display, two-dimensional situation display, and radar signal display.

[0070] During simulation, the radar operating mode control is achieved through manual selection. The user can switch modes through the simulation interface during the simulation process. The operating parameters of various modes are set through the interface during radar initialization, mainly including signal patterns, signal processing methods, data processing methods, waveform arrangement, tracking templates, and specific algorithm parameters, etc.

[0071] The target list display, PPI display, and two-dimensional situation display use different methods to display the targets captured by the radar. The target list display shows information such as target batch number, time, azimuth, distance, altitude, speed, etc. line by line; the PPI display simulates the plan position indicator of the radar and displays the detected target point track information in polar coordinates (azimuth angle, distance) within multiple concentric circles centered on the radar antenna; the two-dimensional battlefield situation display is based on a two-dimensional map and shows the deployment and tracks of the combat platforms of both friendly and enemy sides detected by the early warning radar with the early warning aircraft as the center. In the PPI display and two-dimensional situation display, information such as the target batch number, flight altitude, flight speed, etc. can be marked through labels. The radar signal display mainly shows the waveform and spectrum of the radar transmitted signal.

[0072] S3. Generate radar interference signals according to the battle situation parameters and simulation data information;

[0073] Among them, in step S3, the radar interference signals include echo signals, interference signals, and clutter signals.

[0074] S4. Calculate and process the radar interference signals to obtain radar processing data;

[0075] Among them, in step S4, the calculation and processing of the radar interference signals include using space-time two-dimensional processing algorithms, time-domain accumulation processing algorithms, or over-the-horizon processing algorithms.

[0076] S5. Determine whether the simulation is completed; if the simulation is not completed, return to execute step S2;

[0077] S6. If the simulation is completed, display the radar processing data to obtain the simulation test results.

[0078] The present invention provides an example of demonstrating this technical solution by taking the capture and tracking of a single aircraft target by the early warning aircraft radar under the conditions of with and without interference:
