Abstract: In order to quantify the anti-jamming performance of radio fuze effectively, a similarity-based quantification method of radio fuze anti-jamming performance is proposed based on the definition of the radio fuze target function. The target function is determined through the analysis of the normal target echo signal. The similarity between this target function and output signals of fuze transceiver correlation channel under different types of information jamming are calculated separately. The smaller the similarity under a certain type of information jamming is, the stronger the anti-jamming performance is, and the weaker it is conversely. The proposed quantification method is validated on a continuous wave Doppler fuze for ground-to-ground projectile. Calculation example indicates that this method is objective, reasonable and operability, and can quantitatively evaluate the fuze anti-jamming performance under different types of jamming. Key
