High-Resolution Bistatic Radar Imaging in Support of Asteroid & Comet Spacecraft Missions
نویسندگان
چکیده
High-resolution imaging of potential targets in advance of any spacecraft mission is important for reducing mission cost and risk and improving science returns. In particular, ground-based radar imaging provides highly-accurate ephemerides and shape and spin state information for objects that pass near the Earth. At higher resolution, radar images show surface features such as boulders and potential fissures and constrain internal structure. Examples of radar observations of objects prior to spacecraft arrival include Itokawa [1], Bennu [2], Toutatis [3,4,5], and 103P/Hartley 2 [6].

PASSIVE ASTEROID RADIO TOMOGRAPHY WITH THE JUPITER-IO CMI T. Marshall Eubanks, Asteroid Initiatives
Introduction: An important goal in the in situ exploration of asteroids by spacecraft is the determination of not just the surface characteristics of a target asteroid, but also its interior structure, such as density, porosity and compositional changes at depth. Information about the complex dielectric constant along a raypath, which is related to these quantities, can be determined by monitor...
متن کاملRadio reflection imaging of asteroid and comet interiors II: Results and recommendations
We modeled orbital surface-penetrating radar of an asteroid and comet using two-dimensional finite-difference wavefield migration, in order to assess key target properties and experiment parameters required to fully image internal structure. Migration places radar echoes in their correct positions in a complex subsurface and is a complementary tool to travel-time tomography. The target shape wa...

Answering fundamental questions about the origin and evolution of small planetary bodies hinges on our ability to image their surface and interior structure in detail and at high resolution. The interior structure is not easily accessible without systematic imaging using, e.g., radar transmission and reflection data from multiple viewpoints, as in medical tomography. Radar tomography can be per...

These algorithms provide estimates of spacecraft relative motion and absolute position used to guide the spacecraft during autonomous landing and explorat...
متن کاملOptical-radar imaging of scale models for studies in asteroid astronomy.
During the past five years, delay-Doppler radar has become the primary technique for studying the structure of Earth-crossing asteroids. None of these objects has yet been visited by spacecraft, so ground-truth test cases are lacking. A laboratory system is described that provides optical-radar images at 0.1-mm resolution. These data are analogous to the highest-resolution asteroid radar images...
