摘要
介绍一种基于微机的雷达PPI光栅扫描显示系统的设计与实现。研究了坐标快速转换、数据实时采集等关键技术,提出了优化查表法坐标转换方法以及回波数据的实时采集方案,很好满足了PPI光栅扫描显示系统中高速率、低存储量以及实时性的要求。研究成果已成功应用于某型号雷达PPI显示系统中。
The design and realization of PPI signal raster scan radar display system was introduced, and the key technologies of coordinates conversion and data real-time acquisition were analyzed too. An optimal table look-up method and a real-time data acquisition technical scheme were proposed. The methods were successfully used in a PPI signal raster scan radar display system on active service, and well fulfilled the high-speed, low-memory, and real-time requirements of raster scan radar.
