Research on Flat Earth Removal Techniques of INSAR

Abstract:

As a new microwave remote sensing technique, synthetic aperture interferometry has been developed rapidly in last thirty years. It is based on synthetic aperture. The imaging algorithm of the synthetic aperture radar interferometry (INSAR) is introduced. Two approaches of flat earth removal are derived and compared. The influence of the flat earth removal processing to the interformetry phase statistics distribution and phase derivative is analyzed. The results indicate that the flat earth removal technology makes the phase unwrapping easier and improves the precision of it.
