Radar Imaging 04 - 3-D SAR Imaging Reconstruction - Intuition and Theory 

In the fourth video, we finally delve into 3-D imaging radars starting with reconstruction algorithms for Synthetic Aperture Radars. I start by developing a universal signal model for FMCW, Pulsed and Stepped Frequency radars. This model is then used to develop the Back-Projection, Delay-And-Sum, Time-Domain-Correlation and Matched-Filtering algorithms. They are shown to be mathematically identical in terms of reconstruction. I end with the motivation for developing faster algorithms like Range Migration, omega-K etc. which I will go into in a later video. I will follow up soon with MATLAB, HFSS and Experimental data imaging in another video. Enjoy!
Feel free to catch any other calculation errors or mistakes and post them in the comments.
