Target Recognition Technology of Pulse Doppler Radio Fuze Based on Bandwidth Characteristics for Anti-Chaff Jamming

In order to improve the anti-chaff interference ability of fuze, this paper studies the target recognition technology of pulse Doppler (PD) radio fuze based on bandwidth characteristics. By establishing the aircraft target and chaff interference model, the bandwidth characteristics of the theoretical formula of AM bandwidth and FM bandwidth are simulated. Combined with Kruskal-Wallis statistical test and BP neural network, the method can verify the target and chaff interference. Experiments show that the AM bandwidth and the FM bandwidth have significant differences in the target and chaff interference. After the AM bandwidth and the FM bandwidth are input into the BP neural network, the target and the chaff can be accurately identified.
