In this paper, a near-field high-speed target InISAR imaging method based on wavenumber domain interpolation is proposed. The focusing of the ISAR image is accomplished by performing Stolt interpolation on the echo signal in the wavenumber domain. Three-dimensional imaging is achieved by interferometric imaging algorithms. The algorithm simulation is carried out using the scattering point model generated by the electromagnetic simulation software, and the validity and stability of the algorithm are verified.
