Long wavelength airborne single-pass InSAR systems call for very accurate SAR focusing and motion compensation algorithms. We have analyzed 3 different techniques and evaluated their performance using real data acquired with an L-band single-pass interferometer in Canada. Time domain backprojection with terrain-dependent motion compensation shows the best performance with results close to the theoretically expected values.
