Furthermore, the optical delay lines can provide the immunity to electromagnetic interference and the squint-free wide instantaneous bandwidth required in the high-performance radar systems.

特别是光纤延迟线还能提供高性能雷达系统工作时需要的无偏斜宽瞬时带宽以及抗电磁干扰的能力。

The ionosphere contamination imposing on the High-frequency(HF) radar echoes has to be suppressed since it severely degrades the detection performance of HF radar.

高频雷达回波信号受到电离层污染从而影响了雷达的探测性能，因此需要进行去污染处理。

During the near three decades, high - frequency ground wave radar detecting for sea has been regarded for its high performance by many countries.

近三十年来，高频地波对海探测雷达因其本身所特有的优点而引起了许多国家的高度重视。
