Hybrid CramÉr-Rao Bounds for Crustal Displacement Field Estimators in SAR Interferometry
This paper focuses on the performance achievable by spaceborne Synthetic Aperture Radar Interferometry (InSAR) in the estimation of line-of-sight crustal deformations from acquisitions over a distributed scatterer. Our model is suited for exploiting the Hybrid Cramér-Rao Bound (HCRB), where the unknowns are both deterministic parameters and stochastic variables. We take into account both target...
متن کاملInterrelationships Between Topography, Quaternary Vertical Displacement, Active Faults and Short-term Horizontal Crustal Strain in Honshu, Japan
Regional and local characteristics of active fault patterns and elevation variation throughout Honshu, Japan are characterized in terms of their fractal dimensions; this allows variation in these complex variables to be compared directly to the scalar properties of net Quaternary vertical displacement, elevation and 10and 110-year horizontal strains. The comparisons reveal that, throughout Hons...
متن کاملThe Crustal Structure
This thesis consists of three papers examining problems related to the crustal structure, isostasy and subsidence history of aseismic ridges and mid-plate island chains. Analysis of gravity and bathymetry data across the Ninetyeast and eastern Walvis Ridges indicates these features are locally compensated by an overthickening of the oceanic crust. Maximum crustal thicknesses are 15-30 km. The w...

متن کاملEarly Crustal Evolution of Mars1
■ Abstract The bulk of the ∼50-km-thick Martian crust formed at ∼4.5 Gyr B.P., perhaps from a magma ocean. This crust is probably a basaltic andesite or andesite and is enriched in incompatible and heat-producing elements. Later additions of denser basalt to the crust were volumetrically minor, but resurfaced significant portions of the Northern hemisphere. A significant fraction of the total t...
