[0062] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0063] Example 1

[0064] like Figure 1 As shown, a radar simulation training system provided according to the present invention includes: a guidance and control evaluation subsystem, a target and environment simulation subsystem, a radar simulation training subsystem, and a target data processing subsystem;

[0065] The guidance, control and evaluation subsystem is used to organize and initiate training tasks;

[0066] Specifically, the guidance and control evaluation subsystem has four core functions: training plan formulation, guidance and control, information management, and training evaluation. The subsystem realizes training effect evaluation by collecting evaluation data from various positions; improves the flexibility of obtaining evaluation results by storing training evaluation results in the warehouse; and configures the remote control interface to implement the training task initiation and evaluation result viewing functions on any computer terminal in the local area network, thereby realizing autonomous training of trainees and reducing dependence on guidance and control personnel during training. Thus, a flexible and appropriately configurable simulation training guidance and control evaluation platform for participating technical personnel is constructed.

[0067] The target and environment simulation subsystem is used to simulate the target and atmospheric environment and send scene data messages. As the core of the system simulation environment, the target and environment simulation subsystem undertakes two core tasks:

[0068] Provide the system with benchmark data of targets and environment: it not only supports the simulation of normal target movement, but also has the full-process simulation capability of launching new targets under command control, and calculates and outputs target position, posture, feature information and environmental status data in real time;

[0069] As the system simulation data center, it manages the simulation status of each member of the current training scenario in a panoramic manner, monitors the current status of simulation resources, and enables various simulation entities to advance collaboratively in a unified space and time.

[0070] The radar simulation training subsystem includes functions such as target detection simulation, radar parameter setting, and detection effect display.

[0071] The target data processing subsystem implements target monitoring, carries out surveillance mission planning, target characteristic measurement and accumulation, and target information fusion.

[0072] Specifically, the guidance, control and evaluation subsystem is used to organize and initiate training;

[0073] First, configure personnel authority, target cataloging, simulation entity parameters and other basic data as well as training positions through the information management module of the guidance, control and evaluation subsystem, formulate training outlines, training content, training subjects, training evaluation plans and training plans; secondly, set radar and target parameters and generate training assumption documents through the training plan formulation module, support three-dimensional display of target trajectory, and visibility analysis between simulation entities and targets; finally, establish training rooms through the guidance and control module, organize training, and issue assumption documents to each subsystem and training positions; the system status is set to start successfully;

[0074] The training assessment module of the guidance and control assessment subsystem collects data, including the training data of each operating position and the results of target analysis. By building a training assessment system, a comprehensive assessment is conducted on the radar equipment operation ability and collaborative execution ability of technical personnel in each position, and an assessment report is generated and published.

[0075] Specifically, the target and environment simulation subsystem is used to perform target and environment simulation;

[0076] The atmospheric environment simulation module, space environment simulation module and target and characteristic simulation module of the target and environment simulation subsystem receive and parse the assumption documents issued by the guidance and control evaluation subsystem. The above modules complete the initialization of the simulation environment, the initial position and initial characteristics of the target according to the simulation entity and target parameters and environmental data contained in the assumption documents; the collaborative simulation engine module receives the guidance and control instructions (start, pause, speed change, time jump) sent by the guidance and control evaluation subsystem, and the target and environment simulation model performs position and attitude recursion, simulates the radar characteristics of the target and updates the entity status in real time; receives radar status information, calculates radar field of view targets, completes radar field of view target screening, and finally the target and environment simulation subsystem updates the target data in the scene data based on the screened target data, and sends the updated scene data to the radar simulation training subsystem in the form of a message;

[0077] Specifically, radar simulation training subsystem is used to realize radar simulation target reconnaissance simulation;

[0078] The radar simulation training subsystem interacts with the target and environment simulation subsystem. First, the data processing module receives the scene data message transmitted by the target and environment simulation subsystem, and the target detection module sets the radar search screen and other parameters to display the scene target situation. Then, the target detection module detects, searches, tracks and identifies the scene targets within the radar field of view, and displays the situation. The data processing module generates the target radar characteristic curve and image. Then, the radar simulation training subsystem sends the radar measurement data and radar parameter information to the target data processing subsystem.

[0079] Specifically, the target data processing subsystem is used to realize information fusion and form the target analysis results;

[0080] The system monitoring module and data management module of the target data processing subsystem respectively monitor and manage the interactive data of the system, which are mainly used for system interactive data status judgment and interactive data management display, and are the basic guarantee for system operation. The target data processing subsystem provides high-precision orbit target information preprocessing services for the radar simulation training subsystem through the target information processing module. The information fusion module fuses the radar target measurement data transmitted by the radar simulation training subsystem with the target measurement data of the target monitoring system of other physical mechanisms through multi-feature fusion to form the target judgment result;

[0081] Specifically, the scenario management function of the guidance, control and evaluation subsystem is used to add training entities and goals in a visual form to visualize the training plan and package the scenario information.

[0082] The control of the start of training and its running status is specifically reflected in the fact that the guidance and control module of the guidance and control evaluation can use the assumed scenario as a simulation scene template, create multiple simulation scene rooms, and implement simulation process control such as start, pause, time jump, and speed increase for multiple scenes.

[0083] Environment and target simulation is specifically manifested in its ability to support the coupling of physical factors in multiple scenarios and the training mission scenario requirements of a large number of high-simulation and massive low-simulation targets.

[0084] Target recognition and the generation of target radar characteristic curves and images, specifically manifested in the target's RCS, one-dimensional image and two-dimensional image.

[0085] Feature data fusion, specifically, is the fusion of radar data with data from other monitoring systems, giving the system a more complete target detection capability.

[0086] The present invention also provides a radar simulation training system, which can be implemented by executing the process steps of the radar simulation training method, that is, those skilled in the art can understand the radar simulation training method as a preferred implementation of the radar simulation training system.

[0087] Those skilled in the art know that, in addition to realizing the system and its various devices, modules, and units provided by the present invention in a purely computer-readable program code, the system and its various devices, modules, and units provided by the present invention can be completely realized in the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers by logically programming the method steps to realize the same functions.

[0088] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present invention. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.
