render a synthetic aperture radar image in matlab

To render a Synthetic Aperture Radar (SAR) image in MATLAB, you need to follow the following steps:

1. Load the raw SAR data:

main.m
fileID = fopen('filename','r','n','UTF-8');
data = fread(fileID);
fclose(fileID);
82 chars
4 lines

2. Apply Range Compression to remove the unwanted pixel data:

main.m
data = fftshift(fft2(data));
29 chars
2 lines

3. Apply 2D Fourier Transform for imaging:

main.m
image = ifft2(ifftshift(data));
image = abs(image)
51 chars
3 lines

This should provide you with a basic SAR image. However, SAR can be a complex and nuanced field, depending on your data sources, processing needs and imaging goals. You'll find plenty of good resources and examples on the Mathworks website and discussion groups.
