摘要
对合成孔径雷达实施有效的电子防护,使之具有降低(消除)非人为电磁干扰和人为电磁干扰的能力,是保证合成孔径雷达发挥正常性能的重要条件之一。对非人为电磁干扰抑制的发展现状进行总结,将干扰抑制分为参数化方法和非参数化方法,分别讨论了参数化抑制方法中的干扰建模、参数估计以及非参数化抑制方法的两种主要技术途径,分析了干扰抑制效果的评估方法。最后根据实践和经验提出了合成孔径雷达干扰抑制的几项建议,对今后的发展趋势进行了展望。
Effective electronic protection for synthetic aperture radar can greatly reduce the influence of nonhostile and hostile electromagnetic interference,and it is one of important factors to ensure the synthetic aperture radar to work in its normal performance.The methods of nonhostile electromagnetic interference suppression are summarized and classified into two classes:parametric methods and nonparametric methods.The interference models used in parametric method,the methods to estimate the parameters of the models and two main approaches of nonparametric methods are discussed respectively.On this basis,the approaches to evaluate the performance of interference suppression are analyzed.On the basis of experiments,several suggestions for interference suppression are proposed.
