Anti-sweep Jamming Method for Frequency-modulated Fuze Based on Sparse Bayesian Learning
The frequency-modulated continuous-wave(FMCW)fuzes exhibit deficiencies in anti-sweep jamming in complex electromagnetic environment. To address this issue
an anti-jamming method integrating time-domain interference excision and sparse signal reconstruction is proposed. The high-intensity interference pulses in the time-domain differential frequency signal are accurately located and zero out using the SumThreshold algorithm
thereby fundamentally eliminating the jammingˊs impact on ranging. Subsequently
the sparse Bayesian learning(SBL)algorithm is introduced to tackle the sparsity issue arising from signal loss post-excision. SBL algorithm is used to efficiently reconstruct the target two-dimensional matrix by establishing a Bayesian inference model and optimizing the hyperparameter estimation
thus overcoming the velocity measurement ambiguity. The simulated and measured resukts demonstrate that the SBL-based anti-sweep jamming method has strong robustness. It can accurately recover the target range and velocity information even under the conditions of low signal-to-noise ratio and high sample zero-setting rate. Furthermore
The peak-to-sidelobe ratio(PSLR)achieved with this method is superior to those of several existing mainstream algorithms
significantly enhancing the detection reliability and anti-jamming performance of fuze in harsh electromagnetic environments.
