Implements basic range-Doppler algorithm for focusing RAW SAR image

This function implements 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.
The inputs are the baseband raw data and 8 parameters that describe the SAR (sampling frequency, PRF, range chirp bandwidth, etc.) The output is the singl-look-complex (SLC) focused image.

This code was written for educational purposes and for the sake of clarity, hence many routines can be improved for better performance

Hi Mario,

Thanks for uploading this helpful piece of code. But I would still like to know which raw data product exactly did you use to test this processor. Could you please recommend any?



I would like to thank Mario for all his expertise and assistance. I have also found his SAR processing codes very helpful.


its nice to see the code,
I need to have the sample airborne data on which this code can be applied and found the result.
please assist

Hi everybody. I have downloaded & run this file but I don't know how to input baseband raw data and other parameters. Somebody can help me? Thank.
