Active Technology Project

Project Introduction

Validation and Sensitivity Analysis of 3D Synthetic Aperture Radar (SAR) Imaging of the Interior of Primitive Solar System Bodies: Comets and Asteroids

This task will demonstrate that using Radar Reflection Imager Instrument in an orbing platform , we can perform 3D mapping of the Cometary Nucleus.

To probe the interior of a comet, we are going to employ Radar Reflection Imager (RRI) Instrument on an orbiting platform. While orbiting around the comet at a safe distance of about 20 kilometers , the RRI will transmit electromagnetic waves and receive returned signals from the comet 's surface and the interior. After operating RRi for about 45 days, we would collect almost a million data sets from all sides of the comet. We will develop a technique which will allow us to process the million data sets altogether in order to construct Computer Aided Tomography-like images of the cometary nucleus.
