SAR Imaging Enhancement with Range Doppler Algorithm and Fractional Fourier Transform

Range Doppler algorithm from synthetic aperture radar raw data is processed to produce the final image. The filtering algorithm based on Fourier domain is running for the azimuth and range. To save time fast Fourier transform in the azimuth-frequency and time-range domains for range cell migration correction is used. This domain, Range Doppler domain is called and range cell migration correction is defined and implemented in this domain. Synthetic aperture radar images to improve the clarity of this paper and the algorithm using fractional Fourier transform compared to the classical Fourier transform method is implemented.
