6229 在深入研究间歇采样转发干扰(interrupted-sampling repeater jamming,ISRJ)的基础上,针对ISRJ时域不连续采样的特点,提出一种基于脉内步进线性调频(linear frequency modulation,LFM)波形的抗ISRJ方法。 Forward in the further study of intermittent sampling disturbance (interrupted - from repeater jamming, ISRJ), on the basis of according to the characteristics of the discontinuous ISRJ time-domain sampling, based on a reef stepper linear frequency modulation (linear frequency modulation, LFM) waveform ISRJ resistance method.
6230 该方法利用脉内步进LFM子脉冲之间的正交性互相掩护,子脉冲间频率步进使得干扰采样段经调制后仍无法干扰相邻子脉冲,从而可以有效提取干扰机没有采样的信号段,在对抗高占空比的重复转发干扰时优势明显。 Within the method using pulse stepper LFM pulse the orthogonality between the cover for each other, pulse frequency sampling step makes interference between section can not interfere with the adjacent sub pulse after modulation, which can effectively extract the jammer without sampling signal period, in the fight against Gao Zhankong obvious advantages than when repeat forwarding interference.
