SAR filtering represents a classical frequency domain filtering algorithm widely applied in signal processing. This algorithm demonstrates exceptional effectiveness in removing noise and interference from signals, significantly improving signal quality and clarity. In SAR image processing, SAR filtering serves as a crucial technique that enables better analysis and interpretation of information contained within SAR images. The algorithm typically involves Fourier transformation to convert spatial domain data into frequency domain, followed by frequency domain filtering operations using window functions or filter banks, and finally inverse Fourier transformation to restore the processed spatial domain data. Mastering SAR filtering algorithms is therefore essential for extracting valuable information from SAR images, with common implementations involving functions like fft2() for 2D Fourier transform and carefully designed frequency domain masks for selective filtering.
