DESCRIPTION:Radar is a powerful tool for observing planet Earth from orbit
 . It has become one of the key techniques for understanding our planet\, h
 owever all current radar missions are in low Earth orbit (LEO). From LEO\,
  a satellite has global coverage every few weeks because its orbit is so l
 ow\, and it cannot directly observe rapid processes such as weather during
  a day. Most weather satellites are in geosynchronous orbit (GEO) since th
 is gives a permanent view of about a third of Earth&rsquo\;s surface &ndas
 h\; but there are no radars\, yet\, in GEO. Designing a radar mission for 
 GEO takes us back to the basic principles of radar: we can&rsquo\;t simply
  adapt how we think for LEO radar\, and our understanding of how to implem
 ent GEO radar is still evolving. This talk will cover the principles\, cha
 llenges\, potential\, and prospects for radar imaging from GEO.
