A New Method of Denoising Processing for Synthetic Aperture Radar Return Signal
In this paper, a denoising processing method for synthetic aperture radar raw return signal is proposed based on the DFT-DWT transform. Compared with presented transforms of DFT and DWT, the DFT-DWT transform is more efficient to extract the SAR raw return signal which is a complex 2-D signal with different properties between the two directions. After removing the out-of-band and high-frequency part of the SAR return signals DFT-DWT transform, the noise can be eliminated efficiently. Experimental results verify that the SAR denoising processing method has a practical value for suppressing the suppression jamming and detecting the weak targets.
