| 摘 要： | 由于战场电磁环境复杂,使得在某些频段上雷达信号受到了干扰而无法用于成像。如果仅利用单部雷达在可用频段上的回波信号进行成像,则图像的分辨率无法满足实际需求。为了综合利用多部频带缺失雷达的信号,将频带缺失的多雷达信号融合问题转化为一个信号表示问题。为了增强目标特性,将合成孔径雷达(synthetic aperture radar, SAR)图像增强技术引入到多雷达信号融合处理中,用正则化方法来增强目标的点特性和边缘特性。此融合处理方法不仅适用于多部频带缺失雷达的信号融合,而且无需极坐标插值来完成相位解耦,更能增强目标特性。仿真实验验证了本文方法有效性。

| Abstract: | Because of the complicated electromagnetism environment of battlefield,radar signals in some frequency-bands cannot be used for imaging due to interference.If the echo signal of a single radar in available bands is used for imaging,the image resolution may not satisfy practical requirements.To synthetically utilize multi-radar signals,the problem of multi-radar signals fusion with frequency-band omissions is transformed into a signal representation problem.On the other hand,the synthetic aperture radar(SAR)... |
