Considerations on Complicated Wave Antijamming of Digital Store Frequency
摘要
Abstract
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.关键词
