Abstract :
In the recent years there has been growing interest in exploiting the advanced multibaseline operation of synthetic aperture radar interferometry (InSAR) to solve layover effects that can degrade conventional InSAR imagery. In this work we consider detailed modelling of this problem including speckle noise for extended targets, application of several non-parametric and parametric spatial spectral estimation methods to multibaseline layover solution, and system trade-offs analysis. Corresponding statistical accuracy of estimated heights is investigated by simulation
