基于OSG技术雷达终端显示软件设计

Design of Radar Terminal Display Software Based on OSG Technology

雷达终端主要用来显示雷达视频回波数据,雷达操作员通过观察雷达终端显示的视频回波来确定发现的目标以及目标的位置。传统的雷达视频回波显示方式是利用硬件技术在光栅显示器上实现,随着计算机技术的发展,雷达终端软件化显示已经成为一种趋势。提出基于OSG技术实现雷达视频回波显示,从雷达数据接收、坐标变换、纹理生成、多线程处理等环节阐述整个雷达终端显示软件设计过程。利用OSG的多重纹理混合技术实现了雷达视频与目标信息叠加显示,采用多线程处理方式提高了软件的稳定性和负载能力,此外软件还实现了雷达回波局部三维显示。通过测试,软件从网络中接入雷达实测数据,能够实时绘制和刷新雷达视频。画面显示清晰流畅,没有出现抖动现象。

Radar terminal was mainly used to display radar video echo data,radar operator determined the target and its location by observing the video echo displayed by radar terminal.The traditional radar video echo display mode was realized by using hardware technology on raster display.With the development of computer technology,the software display of radar terminal has becoming a trend.It proposed to realize radar video echo display based on OSG technology.It described the whole design process of radar terminal display software from radar data reception,coordinate transformation,texture generation and multi-threading processing.The multi-texture mixing technology of OSG was used to realize the overlay display of radar video and target information.The multi-thread processing method improved the stability and load capacity of the software.In addition,the software also realized the local three-dimensional display of radar echo.Through testing and software accessing radar data through network,the software can draw and refresh radar video in real time.The picture showed clearly and smoothly without any jitter.
