| Abstract: | According to the technical features of wireless TT&C equipment, this paper analyzes two ways of anti-jamming. The first way is to obstruct the jamming signal, such as topography 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 hopping/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. |
