Radar Imaging 07 - Range Migration, Omega-K and Holographic Reconstruction for FMCW 3-D SAR Imaging

In the seventh video, we discuss a few fast reconstruction algorithms for 3-D SAR imaging. We show that range migration, omega-k and holographic reconstruction all essentially reach the same final result using different derivations. This video is on the theory. In a subsequent video, we will look at the code and work with some experimental data.

Reference 1) is part of my own work so it closely follows the derivations here but there are minor differences. Appendix in ref 2) deals with method of stationary phase in more detail.
