| 摘 要： | 介绍一种基于PC的PPI显示系统的设计与实现。为满足雷达回波实时显示的要求,研究了距离-方位极坐标与光栅显示直角坐标的快速转换算法;为实现传统PPI显示器荧光点余辉效应的模拟,提出了基于回波数据上报周期递减显示像素色深的方法;为满足叠加数字地图和航迹等信息的要求,提出了基于图层的显示数据管理算法。文中提出的设计和算法较好地满足了上述功能和性能要求,研究成果应用于某目标探测系统取得了较好的效果。

| Abstract: | The design and implementation of PPI displaying system based on PC is described.The range-bearing polarizing coordination and raster displaying orthogonal coordination fast conversion algorithm is studied for real time displaying requirement of radar echo.Periodic echo data is applied to drive the descending of pixel color depth to satisfy fluorescence spots persistence vision analogue of traditional PPI display.Displaying data management based on layers is introduced for solution of overlapping of digital map and trace.The design and algorithm described could meet the abovementioned function requirement.The research result is applied to some kind of detection system and works well. |
