Abstract
SAR interferometric surveys are affected by several sources of decorrelation noise. An improvement of the phase accuracy can be achieved by minimizing that noise: this could require a careful "tuning" of some processing dependent parameters. Beside a phase preserving focusing. The sensitivity of coherence with respect of processing parameters is studied, and techniques are presented to minimize the effect of different decorrelation sources.Keywords
