Description

TECHNICAL FIELD

[0001] The present application relates to the field of radar system simulation and verification, and discloses a multi-node data verification method and device for a radar function logic model. BACKGROUND

[0002] As a core detection device in air combat systems, the accuracy of the function logic and the stability of the processing algorithm of the radar can provide support for combat simulation, radar system design and debugging. Currently, the verification of the radar function logic in the industry mostly adopts a single-node independent verification mode, which has the following significant limitations: 1. The existing verification is mostly based on simplified static scenes such as a single target and a fixed trajectory, and cannot simulate the complex environment of dynamic confrontation between the "red side" and the "blue side" in air combat, which makes it difficult to verify the adaptability of the model in actual multi-system cooperative scenes.

[0003] 2. In traditional verification, data is mostly transmitted between the model and the scene and the data processing system through serial ports or TCP protocols. The connection establishment and retransmission mechanism of the TCP protocol introduces millisecond-level delay, which cannot meet the real-time requirements of "detection-processing-control" in air combat scenes, and thus affects the accuracy of the verification results. 3. The existing verification only performs simple comparison on the original target data output by the radar model, does not introduce a "comprehensive processing unit" similar to an actual radar system, and lacks target detection and tracking processing of the target data, which makes the verification results unable to reflect the data processing logic of the radar in actual work.

[0004] 4. The verification of traditional data processing functions relies on actual products and flight test data, and the operating personnel cannot verify the scenes missing in the flight test data, nor can they verify the running logic and data processing algorithm of the products in advance, which affects the product development progress and quality. SUMMARY

[0005] The present application aims to solve the technical problems of the existing verification scenes being disconnected from reality, insufficient real-time data transmission, simplified data processing links, and lack of visual monitoring in the verification process, and provides a multi-node data verification method and device for a radar function logic model.

The multi-node data verification module is configured to transmit data information of the red aircraft and the blue aircraft to the radar function logic model, and process the data information through the radar integrated processing system function logic model, so as to realize multi-node data verification of the radar function logic model.

[0012] As a preferred embodiment, the modeling tool in the model construction module is an Rhapsody tool, and the model construction module further comprises an algorithm code integration submodule, which is configured to integrate algorithm codes in a state machine model of the radar function logic model in a manner of calling a preset dynamic link library or embedding a radar behavior algorithm in a module graph of the radar function logic model.

[0020] REFERENCE Figure 1, Embodiment 1, a multi-node data verification method of a radar function logic model, which realizes multi-node collaborative verification through five core steps of "model construction-scene building-channel establishment-data processing-monitoring verification", specifically comprising: Step one, model construction step A radar function logic model and a radar integrated processing system function logic model are constructed through a modeling tool, and the modeling tool adopts Rhapsody tool which supports system modeling based on UML / SysML and can accurately describe the state conversion and data interaction logic of the radar; Algorithm codes are integrated in the state machine model of the radar function logic model, and the integration mode includes two modes: Call a preset dynamic link library (DLL): encapsulate the core algorithms of radar signal processing and data processing as DLL files, and integrate them into the model through the external code calling interface of Rhapsody to verify the feasibility of the algorithms; Embed the radar behavior algorithm in the module diagram of the radar function logic model: directly write algorithm codes such as radar target search, tracking, and parameter calculation in the model module to ensure deep coupling between the algorithm and the model logic.

[0021] Step two, combat scene construction and model loading An air combat scene is constructed through a simulation scene platform, and the radar model is loaded. The simulation scene platform selects a tool that supports dynamic counter-scene generation, sets a red plane (carrier aircraft) and a blue plane (target aircraft) in the scene, configures the basic parameters of the red plane such as flight height, speed, heading angle, and the dynamic trajectory of the blue plane such as uniform cruise and maneuvering avoidance. The radar function logic model constructed in step 1 is loaded on the red plane, so that the radar model can receive target information such as the position and speed of the blue plane in real time, simulate the use scene and running process of the real radar.

The selection basis of the UDP protocol: UDP is a connectionless protocol, and does not need to establish a handshake connection, which meets the real-time requirements of the air combat scene; at the same time, through custom data frame format, including node identification, data type, timestamp, and verification, the integrity and synchronization of data transmission are ensured; Function of bidirectional data transmission channel: realize the real-time interaction of "data uplink - instruction downlink" between nodes, for example: scene node transmits red and blue aircraft data to radar model node, integrated processing system node issues radar control parameters to radar model node.

[0023] Step four, data processing and multi-node verification Through the radar integrated processing system function logic model to process data, complete the radar model verification, the processing process of the integrated processing system to the data is divided into two steps: ① Target data processing: target detection and tracking processing is performed on the blue aircraft target data received by the radar function logic model, and target tracking results such as target distance, radial velocity, azimuth angle, and pitch angle are generated; ② Data interaction feedback: the target tracking results are fed back to the avionics display and control interface for the operator to view; the radar control parameters are issued to the radar function logic model to adjust the working mode of the radar, forming a "detection - processing - control" closed loop verification.

[0024] Real-time monitoring step: monitor the whole process through the avionics display and control interface, the display content of the avionics display and control interface includes: real-time position, speed, attitude of red aircraft, detection target data and state data of radar function logic model; Interface supports parameter configuration, such as modifying radar working mode and abnormal intervention, such as pausing verification, switching working mode, improving controllability of verification process.

[0026] The avionics display and control module 5 is further used for real-time control of the radar function logic model, real-time display of the red plane position and attitude data, and real-time display of the detected target data and state data of the radar function logic model.

[0027] The multi-node data verification module 4 comprises a comprehensive processing submodule 6, which is used for processing data information and specifically comprises the following: A target data processing unit 61 is used for target detection and tracking of the blue plane target data received by the radar function logic model, and generates a target tracking result. A data interaction unit 62 is used for feeding back the target tracking result to the avionics display and control module, receiving the radar control parameters sent by the avionics display and control module, and issuing the radar control parameters to the radar function logic model.
