Radar-Image-Processing-Class

d_R.npy -- a sample data file with microwave holography data (SAR principle)

methods -- a class this methods to preprocess radar data and reconstruct a radar image. The most important method is def focus(self, d) -- it's the backpropagation in Fourier frequency domain from the scanning plane to the object's plane.

For detailed information on radar image reconstruction see the classic work:

or its recent non-destructive testing application in our paper:
