Abstract. The national German weather radar network operates in C-band between 5.6 and 5.65 GHZ. In a radar network, individual transmit frequencies have to be chosen such that radar-radar induced interferences are avoided. In an unique experiment the Hohenpeissenberg research radar and five operational systems from the radar network were used to characterize radar-radar induced interferences as a function of the radar frequency. The results allow to assess the possibility to add additional C-band radars with magnetron transmitters into the existing network. Based on the experiment, at least a 15 MHz separation of the nominal radar frequency is needed to avoid a radar-radar interference. The most efficient mitigation of radar-radar interference is achieved by the "Radar Tango". Latter refers to the synchronized scanning of all radar systems in the network. Based on those results, additional C-band radar systems can be added to the German weather radar network if a further improvement of the radar coverage is needed.

评估和缓解雷达——德国 C 波段天气雷达网络中的雷达干扰

摘要。德国国家气象雷达网络在 5.6 和 5.65 GHZ 之间的 C 波段运行。在雷达网络中，必须选择单独的发射频率，以避免雷达-雷达引起的干扰。在一项独特的实验中，Hohenpeissenberg 研究雷达和雷达网络中的五个操作系统被用于将雷达-雷达感应干扰表征为雷达频率的函数。结果允许评估在现有网络中添加带有磁控管发射器的额外 C 波段雷达的可能性。根据实验，标称雷达频率至少需要 15 MHz 间隔以避免雷达-雷达干扰。“雷达探​​戈”可以最有效地缓解雷达-雷达干扰。后者是指网络中所有雷达系统的同步扫描。根据这些结果，如果需要进一步提高雷达覆盖范围，可以在德国气象雷达网络中增加额外的 C 波段雷达系统。
