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。
Airborne Forwarding Jammer Speeding Spoofing Jamming is a co-channel interference. There are no better measures to combat this type of interference. The results show that anti-Doppler interference circuit composed of cross-coupled phase locked loop (CCPLL) structure can resist such interference under certain signal-to-noise ratio and extract useful weak target echo signal from strong interference.
