Abstract

SAR interferometry requires a thorough phase control throughout the imaging process. The phase accuracy is affected by decorrelation effects between the individual surveys. The paper presents the probability density function of the interferometric phase and analyzes quantitatively the influence of decorrelation. In particular, phase aberrations typical for SAR processors are studied. The dependence of phase bias and variance on processor parameters is demonstrated
