An analysis of real-Fourier domain-based adaptive algorithms implemented with the Hartley transform using cosine-sine symmetries

Range‐dependent semi‐parametric autofocusing for manoeuvring targets inverse synthetic aperture imagery

“…When the number of DCT kernels is set at 10 and beyond, the image quality basically does not improve much, indicating that using 10 DCT kernels, almost all of the uncompensated phase can be fitted. For the selection of the DCT kernels, to achieve the best calculation efficiency and image quality, it needs further selected by an adaptive method [25, 26].…”
