    Abstract

    The transmitted beam of the phased array only has angle dependence.In contrast, Frequency Diverse Array (FDA) adds an increment of frequency offset between the array element to make it display the characteristics of range-angle two-dimensional dependence, which not only solves the problem of angle pointing during beam transmission, but also solves the problem of distance pointing during beam transmission.By introducing MIMO into FDA, the transmitted information can be integrated into the receiver, thus realizing more flexible utilization of range dimension Degrees of Freedom (DOF) and improving the ability of range-angle two-dimensional joint signal processing, which gives FDA-MIMO unique application advantages in countering range-dimension main lobe deception jamming.In view of the good anti-jamming characteristics of FDA-MIMO, the basic principle and model of FDA-MIMO are introduced, the research progress of FDA-MIMO at home and abroad is summarized from the perspective of anti-jamming, the basic principle and main techniques of FDA-MIMO radar anti-jamming are systematically discussed and summarized, and the main application prospects of FDA-MIMO and other FDA radar technologies in anti-jamming in the future are analyzed.
