Two- and Three-Dimensional Fast Intrawall Imaging with Microwave Tomographic Algorithm
International Journal of Antennas and Propagation, 2018 A fast and efficient microwave tomographic algorithm is proposed for 2-D and 3-D real-time intrawall imaging. The exploding reflection model is utilized to simplify the imaging formulation, and the half-space Green’s function is expanded in the spectral ...

Large-scale 3D fast Fourier transform computation on a GPU
ETRI Journal, 2023 We propose a novel graphics processing unit (GPU) algorithm that can handle a large-scale 3D fast Fourier transform (i.e., 3D-FFT) problem whose data size is larger than the GPU's memory.

Efficient Algorithm for SAR Refocusing of Ground Fast-Maneuvering Targets
Remote Sensing, 2019 The synthetic aperture radar (SAR) image of moving targets will defocus due to the unknown motion parameters. For fast-maneuvering targets, the range cell migration (RCM), Doppler frequency migration and Doppler ambiguity are complex problems.
