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.
