The method uses general-purpose computer to generate radar echo data, printer interface to transmit data from PC to peripheral equipment, and D/ A converter to form simulated video echo signal. The method is of significant flexibility and commonality. 该方法采用通用计算机产生雷达回波数据,利用打印机接口实现PC机向外设传送数据,采用D/A变换器产生模拟视频回波信号;
