In this paper, we propose a fast and accurate radarimaging algorithm that combines Kirchhoff migration with Stolt's frequency-wavenumber (F-K) migration. F-K migration is known as a fast-imaging method in the F-K domain, while Kirchhoff migration is reported to be more accurate. However, Kirchhoff migration requires the reflection points to be located as a function of the antenna position and the delay time. This prevents the use of fast Fourier transforms (FFTs) because Kirchhoff migrationdoi:10.1109/tap.2015.2431725 fatcat:bj6l23634rbqnbaedpwdqkz44e
