Abstract

This study proposes a sliding multi-cycle fast Fourier transform (FFT) processing method to address the problem of poor performance of the FFT harmonic envelope extraction method used in FM fuze under frequency sweeping jamming conditions. The proposed method aims to achieve effective interference suppression by coherently accumulating echo energy through multi-period FFT processing. The processing data is updated by sliding between adjacent processing windows

and the difference frequency harmonic envelope corresponding to the predetermined blast height is further extracted for threshold judgment. The simulated and measured results show that compared with traditional single-cycle FFT processing method

the new method can effectively extract the target harmonic envelope characteristics under frequency sweeping jamming

significantly improve the peak-to-side lobe ratio

and enhance the anti-frequency sweeping jamming performance of FM fuze.

The ranging principles of the two methods are described, their range resolutions and anti-noise performances are analyzed, and the simulations are carried out to validate these methods. The simulation results demonstrate that the ranging resolutions of the two methods which are affected by the modulation bandwidth rarely are much better than that of the ranging method based on the harmonic wave method. For the known frequency modulation rate, the complexity of the methods is reduced and acceptable for engineering realization. The fractional correlation method is better than the instantaneous initial frequency estimation method in anti-noise performance and can be used in the low signal-to-noise ratio circumstance.
