Review of anti-informational jamming techniques for radio proximity fuze

At present, the information jamming for radio fuze has high efficiency and a remarkable effect, which has attracted the attention of major military powers in the world. In order to ensure the damage efficiency of the radio fuze in the battlefield, the relevant technology of anti-information jamming has become a research hotspot in the field of radio fuzes. This paper introduces the military demand for the fuze against interference and describes the current research status of the radio fuze against information-based interference from the three aspects, namely signal domain, information domain, and antenna selection. There are many problems, such as deterioration of resolution and inapplicability of signal processing methods. Based on the unique “S” curved array pattern of FDA-MIMO (frequency diverse array-multiple in multiple out) technology, the anti-jamming of FDA-MIMO technology is reviewed from three aspects, namely direction-finding deception, low interception point beamforming, and anti-main lobe interference. Finally, the anti-information jamming technology of a radio proximity fuze based on FDA-MIMO is prospected.
