機載相控陣雷達系統(tǒng)功能級建模與仿真
[Abstract]:Because of the successful application of APG-77 radar in the F-22 fighter, and the computer simulation technology is applied to the real-time simulation of radar algorithm and system, the function level simulation system of airborne phased array radar is based on the Visual Studio 2010 platform, and has completed the red and blue confrontation through the testing of the radar function module and system. Real time simulation is of guiding significance for the research of strategic warfare method. Firstly, the selection of pulse repetition frequency is different, the location of the clutter in the target is different, and the three working modes are combined with search and tracking, edge scan tracing and sudden detection, and the overall scheme of red and blue confrontation and the function level imitation of single airborne radar are put forward. The overall composition of the real system, standardizes the input and output interfaces of the system. Then it introduces the composition model of the system and the main functions of each model, mainly including the phased array antenna model, the coordinate transformation model, the environment echo power generation model, the target detection model, the data processing model, the resource scheduling model, anti stealth model, the anti stealth model, and the anti stealth model. The principle of functional level modeling, such as interference model, is set up based on XML technology to set up the initialization parameters and explain the control interface and display interface. The constructed single radar system is extended to four red square aircraft against four blue-square aircraft, and the four to four target state display and B display are completed. In order to verify the performance of the single airborne radar, the correctness of the antenna pattern is tested first, then the results of the wave position arrangement and the attenuation coefficient of the weather clutter in different weather conditions are tested. Then the airborne radar is compared and analyzed in the three operating modes, and the filtering data is refined under the single target detection. The simulation results verify the validity and correctness of the airborne radar system. This paper is based on the software platform of standardized components, modeling with the idea of modularization, standardization, high cohesion and low coupling, which not only improves the radar system. The model library also implements the new system quickly and conveniently, and enhances the transplantation function of the module.
