SAR Processor

Implements a basic range-Doppler algorithm for focusing raw synthetic aperture radar (SAR) data

This function implements a basic range-Doppler algorithm to focus raw SAR data. It has been successfully tested with L-band airborne SAR data, provided it has low squint.

Inputs are the baseband raw data and 7 parameters that describe the SAR (sampling frequency, PRF, chirp parameters, etc.) A single-look-complex (SLC) focused image is returned as output.

This code was written for educational purposes and for the sake of clarity, hence it can be improved for better focusing and computing performance.
