在许多行政机构中，对正常通信量的无线电中继设备进行操作监视已成为普遍现象。利用无线电帧的奇偶校验特征来导出误码率（BER）的估计，并且随后累积超过特定BER时的事件数（秒）。因此，可以估计特定收发机/无线电跳频的性能是否将满足CCIR建议G.821的要求。所描述的功能由监控系统对所有无线电信道和特定传输系统的所有跳段执行。提出了确定雷达电磁干扰发生的一些方法，以及提取干扰雷达的一些特征的方法。
The operational surveillance of radio relay equipment carrying normal traffic has become common within many administrations. The parity check feature of the radio frame is exploited to derive an estimate of the bit error rate (BER) and subsequently the number of events (seconds) when a certain BER is exceeded is cumulated. Thus one may estimate whether the performance of a particular transceiver/radio hop will meet the requirements of CCIR Rec. G.821. The function described is performed by the supervisory system for all radio channels and all hops of a particular transmission system. Some methods for ascertaining the occurrence of radar EMI, and for extracting some of the characteristic features of an interfering radar are presented.
