Research on simulation of marine radar system based on android

现有的船用雷达模拟器大多是基于桌面系统研发。随着移动互联网的迅速发展,基于移动终端的船用雷达仿真系统具有潜在的应用价值。参照JRC-JMA-9100型号雷达,基于Android移动平台设计并实现了一个船用雷达仿真系统APP。采用一种改进的道格拉斯-普克算法对岸线数据抽稀,使用圆周扫描算法对物标进行扫描求交,提高了雷达模拟器岸线回波的绘制效率。采用瑞利分布、正态分布数学模型,利用模型叠加的方式,实现了海杂波、雨雪杂波的仿真。采用分层显示的方式实现了电子方位线、活动距标圈、平行索引线、自动捕获区、偏心显示等雷达刻度系统功能。仿真结果表明,系统在移动终端上运行稳定,仿真效果良好。

The existing marine radar simulators are mostly researched based on the desktop systems.With the rapid development of mobile internet,marine radar simulation system has potential application value based on the mobile terminal.According to the JRC-JMA-9100 radar,a marine radar simulation system APP is designed and implemented on the Android mobile platform.An improved Douglas-Peucker algorithm is used to simplify the shoreline data.The circular scanning algorithm is used to scan the object and improve the rendering efficiency of the radar image.Using Rayleigh distribution and normal distribution mathematical model,the simulation of sea clutter,rain and snow clutter are realized by model superposition method.The function of radar calibration system,such as electronic bearing line,variable range marker,parallel index line,acquisition zone and off-center are realized by using hierarchical display method.The system runs steadily and the simulation achieves good result on the mobile terminal.
