摘要
针对舰用雷达在编队作战时雷达视频受到同频异步干扰现象,从理论上推导了同频同步干扰和异步干扰的产生机理与特征,为抗干扰计算提供了依据;总结了常用的传统抗同频干扰技术及其缺陷,提出了一种基于相关处理的抗同频异步干扰技术,并进行了电路设计。实际数据验证了该技术有效性。
Aimed at the phenomenon that warship radars are interfered by the co-channel interference,the generation mechanism and characteristics of co-channel interference are calculated in theory,thus providing the foundation for the anti-interference calculation.Then,the traditional anti-interference technologies and their limitation are analyzed.Finally,an anti-interference technology based on the correlation processing is proposed and the circuits are designed.Experimental results prove the validity of the technology.
