| 摘要: |
| 针对无线电测控设备的技术特点，分析了提高抗电磁干扰的两个途径：一是隔断干扰信号
，包括地形和金属屏遮蔽、降低天线副瓣；二是采用信号处理技术剔除干扰的影响，包括跳
扩频技术、信道编码。此外，指出了无线电测控设备根据站址实测电磁环境综合采用这些方
法，能够提高测控设备执行任务的可靠性。 |

| Abstract: |
| According to the technical features of wireless TT&C equipment, this paper analy
zes two ways of anti-jamming. The first way is to obstruct the jamming signal, such as topogra
phy or metal shield and side-lobe reduction.The second way is to use signal
processing technology to eliminate the effect of jamming, such as frequency hopp
ing/spreading and channel coding. It is pointed out that
wireless TT&C equipment can improve its reliability by adopting these methods on
the base of reconnaissance of the given station. |
