Research Of Air Combat Training Condition Real-time Monitoring System

In modern air combat, combat effectiveness of airborne weapons into full play is the key of winning, the major military powers in the world has always attached great importance to air combat tactical combat training and assessment. With the development of science and technology, especially the development of computer technology, has developed a military air combat training system of multiple series, not only the function and performance of increasingly stringent requirements, and performance to more and more close to the actual requirements. In recent years, China’s Air Force combat training development also continued to deepen the quality evaluation results of tactical training has become increasingly important, the degree of dependence on air combat training system continues to increase, due to the existing training equipment earlier, widespread aging equipment, backward technology, has been unable to meet the modernization of the air force training needs. Under this background, the paper studies and designs the air combat training condition monitoring system. The system consists of data acquisition module, airborne weapon module, data processing module, data recording module, power management module, data transmission module and the ground data center, the modular equipment installed in the aircraft interior, and connect with the aircraft data bus, it can collect real-time parameters, aircraft attitude in flight training the location parameter and the weapon parameters, and realize the simulation of Infrared Air-to-Air Missile Detection, intercepting and tracking and emission of the whole process, at the same time, all the data will be transmitted to the ground real-time evaluation system.The main content of this research:1. Research on Tactical Simulation Technology of air combatWhen air to air missile attack training, the use of high cost of infrared guidance device seriously restricts the intensity of training and the level of application. The development of modern simulation technology provides a way to effectively improve the efficiency of air combat simulation training, and plays an important role in the development of modern air combat simulation. Based on the research of tactical air combat simulation, analysis of Infrared Air-to-Air Missile performance parameters, using the method of numerical simulation and qualitative simulation combined, fully consider the influence of solar radiation and other environmental factors, the establishment of Infrared Air-to-Air Missile Detection and interception of mathematical model, simulation of target tracking and launching process. The application of digital simulation technology makes the service life of air combat training equipment extended from dozens to hundreds of flying hours and maintenance is more convenient, reduces the training cost and improves the training efficiency.2. Research on bus technologyA certain type of air combat aircraft for the last century in 90s, equipment, airborne training equipment is less, there is no bus data acquisition and collection equipment, the impact of the air combat training assessment of the accuracy and objectivity of the results. The topic for the technical characteristics of this type of aircraft, in-depth study of GJB289A bus communication technology, air combat training monitoring system design data can be cross-linked with aviation bus, collect and record related training parameters, solve the bottleneck problem of a certain type of aircraft can not achieve the evaluation of total factor attack training. Analysis of the design principle and data format of each airborne data system, taking into account the bus terminal number and work in real time, determined by the interrupt service program for data acquisition, effectively maintain the real-time communication and data.3. Research on wireless communication technologyThe research of the TDMA wireless network communication technology based on high speed data transmission of airborne radio is determined by the training information real-time transmission to the ground data processing center air combat aircraft, the ground commander can effectively monitor the air training situation and training quality evaluation, change the flight training after spending a lot of time for data collection and interpretation the training mode, improve the training efficiency. The research on the design characteristics of communication system networking method, the design scheme of wireless data transmission module, solves the problem of rapid PN code synchronization, effectively improve the anti-interference; in short data frame conditions, proposes to use the TURBO encoding and decoding algorithm to realize.4. Design system engineering implementationOn the basis of analyzing the working principle and related performance indexes of air combat training status monitoring system, the specific implementation methods of hardware and software of the system are put forward. Through the comparative analysis, the design of data acquisition module using SoC FPGA in high speed data processing and the advantages of flexible programming, using 5CSXFC6C6U23ES chip of Altera company as the main control chip; in the design of the data transmission module, the high school frequency is used to filter the interference of the mirror frequency and other frequency to the radio frequency channel.
