基于目标联合特征提取的脉冲多普勒引信抗干扰方法

An anti-jamming method based on the joint feature extraction of target signal for pulse Doppler (PD) fuze is proposed for the inadequate capacity of PD fuze against information type jamming. The output signal of fuze baseband filter is analyzed in consideration with the target function, and an expected target space is constructed using both two-class and one-class support vector machines (SVMs). The proposed method is verified through prototype test. The experimental results indicate that the prototype of PD fuze achieves more than 90 percent success rate in anti-jamming, which can significantly improve the anti-jamming ability of pulse Doppler fuze.
