雷达回波A显在光栅上的实现

The implementation of A-scope of radar echoes on raster monitors

作为雷达回波的一种重要显示模式,A显是重要的目标识别辅助手段。本文介绍了采用SDRAM作为缓存存储器,利用大规模可编程逻辑器件进行控制和处理,在光栅显示器上实现雷达回波A显的一个设计实例。

As an important mode of display in radar system, the A-scope is an assistant means to identify targets. An example of realizing the A-scope on the raster monitor is described with the logical circuits in the FPGA acting as the controlling and processing center, and the SDRAM as the buffer to store the data.
