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.

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.File in questo prodotto:
