| As an important part of the radar system,the radar display terminal always plays a pivotal role in radar data processing.With the vigorous development of computer simulation technology in the field of weapons and equipment,radar combat training have been changed over from practical loading to simulation system.As a key link in contact with trainees,the effect of radar visualization display terminal modeling will directly affect the results of combat training.Due to the complex airspace environment,modern airborne radars already have rapid response capabilities and target processing capabilities.It relies on the cooperation of airborne primary radar(search radar,fire control radar)and airborne secondary radar to search,intercept,track and identify targets.Due to the difference in data format,the modeling of the display control terminal of the traditional airborne primary and secondary radar simulation system is also independent of each other.Therefore,in the integrated simulation exercise,the operators need to take into account a variety of radar display and control terminals,which increases the difficulty of data observation and analysis.In order to improve the comprehensiveness of the display and control terminal of the contemporary airborne radar simulation system,this paper designs and realizes the centralized terminal software.The specific work content is as follows:?Based on the display requirements of airborne primary radar simulation system and airborne secondary radar simulation system,this study analyzes and formulates the functional requirements and structure of the whole software.?In this study,In order to better respond to the continuous simulation requirements,XML technology is used to manage the simulation parameters of primary and secondary mine systems and to dynamically bind them.On this basis,the method of "hash array+time decision" is proposed to optimize and accelerate the parameter binding process.?In the study,a set of situation display terminals that support dual maps are built by embedding GIS components.,which also supports simulation situation deduction for SSR working mode and IFF working mode.?"OpenGL+QChart" visualization technology and multi-threading technology are used to realize the design of layers and graphic elements,including multi-view radar display,airborne primary radar detection information and airborne secondary radar identification information.Specifically covering:target track,target identification code,target status code,antenna beam,antenna pattern,spatial wave position,geographic information,system state,primary radar signal,secondary radar signal and clutter,etc.On this basis,this paper adopts the method of "vertex buffer+ display list" to optimize the data rendering process and improve the overall drawing efficiency of the software.?The interface of data transfer between display control software and background simulation system is designed by using ZeroMQ component.?Firstly,the working process of the airborne secondary radar simulation system is deduced dynamically under the SSR working mode.Then,in IFF working mode,the dynamic simulation of target detection,tracking and identification process is completed by using the coordination mechanism of airborne primary radar system and airborne secondary radar system,and the correctness,reliability and completeness of the display control terminal software are verified.The centralized display terminal software of airborne radar in this paper has the characteristics of comprehensiveness,expansibility and high fidelity.It combines the display and control requirements of airborne primary and secondary radars,and provides a reference for the modeling of visual terminal of radar simulation system. |
