Tomographic inversion of gravity gradient field for a synthetic Itokawa model
Liisa-Ida Sorsa, Mika Takala, Patrick Bambach +6
This article investigates reconstructing the internal mass density of a numerical asteroid model using the gradient of a simulated gravity field as synthetic measurement data. Our…
Far-Field Inversion for the Deep Interior Scanning CubeSat
Mika Takala, Patrick Bambach, Jakob Deller +6
This study aims at advancing mathematical and computational techniques for reconstructing the interior structure of a near earth asteroid (NEA) via Computed Radar Tomography (CRT).…
Multigrid-based inversion for volumetric radar imaging with asteroid interior reconstruction as a potential application
Mika Takala, Defne Us, Sampsa Pursiainen
This study concentrates on advancing mathematical and computational methodology for radar tomography imaging in which the unknown volumetric velocity distribution of a wave within…
The effect of hardware-computed travel-time on localization accuracy in the inversion of experimental (acoustic) waveform data
Mika Takala, Timo D. Hämäläinen, Sampsa Pursiainen
This study aims to advance hardware-level computations for travel-time tomography applications in which the wavelength is close to the diameter of the information that has to be re…
Electromagnetic 3D subsurface imaging with source sparsity for a synthetic object
Sampsa Pursiainen, Mikko Kaasalainen
This paper concerns electromagnetic 3D subsurface imaging in connection with sparsity of signal sources. We explored an imaging approach that can be implemented in situations that…
Orbiter-to-orbiter tomography: a potential approach for small planetary objects
Sampsa Pursiainen, Mikko Kaasalainen
The goal of this paper is to advance mathematical and computational methodology for orbiter-to-orbiter radio tomography of small planetary objects. In this study, an advanced full…
