摘　　要：阐述了数字射频存储器的基本结构,以及干扰的优点和局限性,从设计复杂波形进行反数字储频干扰研究,对阶段相位扰动LFM信号、串并联信号、脉内非线性调频脉间相位编码信号进行了分析。这3种复杂信号能够造成干扰信号和雷达信号失配,弱化干扰和回波的相干度,能够区分出干扰信号和回波信号,达到反干扰的效果,为反数字储频干扰的研究提供理论依据。The structure of DRFM is expounded, the advantage and disadvantage of jamming is introduced, antijamming of digital store frequency is researched based on the complicated wave. Section phase modulated LFM, series parallel connection signal, NLFM in pulse and phase coded among pulses signal are analyzed, which can cause interference signals and radar signals to mismatch, then coherent degree of jam and return signal is weakened by using these three kinds of complicated signals. The interference signals and radar signals can be distinguished, which could achieve the effect of antijamming and provide the theoretical basis for studying antijamming of digital store frequency.
