This process significantly reduces speckle noise, creating a smoother image, but at the cost of spatial resolution. Geocoding and Orthorectification
efficiency of FFT-based algorithms. Modern processing relies heavily on GPU acceleration to make BPA viable for real-time applications. 4. Post-Processing and Image Enhancement digital processing of synthetic aperture radar data pdf

RDA processes SAR data in the range-Doppler domain – after range compression, a Fourier transform is applied in azimuth to convert to the Doppler frequency domain. RCMC is performed by interpolating the data along range bins for each Doppler frequency, exploiting the fact that range migration is a function of Doppler frequency. This process significantly reduces speckle noise
