摘要
机载转发式干扰机施放的速度欺骗干扰是一种共道干扰。目前还没有抗这类干扰的较好措施。研究结果证实,采用交叉耦合锁相环(CCPLL)结构构成的抗共道多卜勒干扰电路在一定信噪比下可抗这类干扰,从强干扰中提取出有用的弱目标回波信号。
The velocity deception jamming released by airborne repeater jammer is of co-channel nature. Up to present, there is no better measure to resist such jamming,Anti-jam-ming circuit using CCPLL demonstrates its ability to extract useful signal from a weak echo under strong jamming above a certain signal to jamming ratio.
