雷达情报串口传输质量检测与评估

Detection and Evaluation of Radar Information Transmitting Quality via Serial Ports

在雷达情报处理系统中,大量采用串口通信方式传输雷达情报。雷达情报串口传输质量是雷达情报处理系统中需要考虑的问题。针对现状,探讨了三种检测和评估串口传输质量的方法即主动方式、被动方式和主被动结合方式,主被动结合检测与评估方法更适合应用于雷达情报处理系统。该方法结合物理层、数据链路层、报文层信息,从误码率、误帧/组率和错报率的角度进行分析,利用串口协议通信服务设备和报文产生器对雷达情报串口传输质量进行检测与评估,已成功应用于实际工程中,收到了较好的效果。

Since radar information is commonly transmitted via serial ports in radar information processing systems, its transmitting quality must be considered. According to reality, three methods are discussed. The method of detecting and evaluating radar information transmitting quality actively and passively combined is more suitable for radar information processing systems. It utilizes communication and service devices to collect information from physical level, data link level and message level. Radar information transmitting quality can be obtained by analyzing the bit error rate, the frame error rate and the message error rate. It has been applied to projects and works well.
