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 goal is to advance the mathematical inversion methodology and find fea

In this paper, we investigate full-wave computed radar tomography (CRT) using a rubble-pile asteroid model in which a realistic shape (Itokawa) is coupled with a synthetic material composition and structure model. The aim is to show that sparse bista

We have performed an initial stage conceptual design study for the Deep Interior Scanning CubeSat (DISCUS), a tandem 6U CubeSat carrying a bistatic radar as main payload. DISCUS will be operated either as an independent mission or accompanying a larg

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). We introduce a far-field model for full-wave CRT and validate it nume

M. Takala, D. Us and S. Pursiainen, "Multigrid-based inversion for volumetric radar imaging with asteroid interior reconstruction as a potential application," in IEEE Transactions on Computational Imaging, vol. PP, no. 99, pp. 1-1, 2018
This study concentrates on advancing mathematical and computational methodology for radar tomography imaging in which the unknown volumetric velocity distribution of a wave within a bounded domain is to be reconstructed. Our goal is to enable effecti

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 recovered. Such can be the case, for example, in the imaging application

Viimeisen kymmenen vuoden aikana pienten ns. nanosatelliittien hyödyntäminen matalalla Maan kiertoradalla on kasvattanut suosiotaan CubeSat-standardin ansiosta. Nämä nanosatelliitit ovat olleet tärkeä osa ns. uutta avaruusteollisuutta, jossa to
