AB  - An anti-sweep jamming method for frequency modulation (FM) fuze based on outlier reconstruction was proposed for the problem of FM fuze against sweep jamming. Based on the iterative filtering decomposition (IFD) algorithm, the intermediate frequency signal of fuze was decomposed into intrinsic mode function (IMF) components. Sweep jamming was represented as outliers in the IMF components. By detecting and eliminating outliers in the IMF components and using a long short-term memory (LSTM) network to build a data reconstruction network model, the data of outliers was reconstructed, and the sweep jamming could be suppressed. The effectiveness of the proposed method was verified by simulation. The results show that the proposed method improves the ability of FM fuze against sweep jamming.
