摘要
Abstract
With the increasingly complex electromagnetic environment,synthetic aperture radar(SAR)is sus-ceptible to interference,which results in significant degradation in imaging quality.In order to address the issue of interference in elevation multi-channel SAR systems,an interference suppression method based on an adaptive noncircular fast independent component analysis(nc-fastICA)algorithm is proposed.Firstly,based on the tradi-tional complex signal nc-fastICA algorithm is presented a Kurtosis-based adaptive nonlinear function selection strategy.Subsequently,combined with the signal model of the elevation multi-channel SAR system,the proposed method is applied to suppress the unintentional interference.Simulation results demonstrate that the proposed method effectively suppresses two types of unintentional interference.In cases where the processing dimension of traditional multi-channel SAR interference suppression methods is limited or their performance is constrained by errors,the proposed approach can improve the interference suppression effect to a certain extent.关键词
