The table below summarizes the main characteristics (where these are known or can be estimated) of the wide-band imaging radars in the Space Surveillance Network. See the posts on the individual systems for details. (Click on the Table for a more legible version)

/ September 11, 2012With regard to Globus II, I’d give it a “probably” for Geo Imaging Capable.
The collection http://www.fas.org/spp/military/program/track/globusII.pdf contains a FOIAed item that says,
“HAVE STARE is an X-Band tracking/imaging radar, with a 27M dish/35M radome, and supports the AFSPC Space Surveillance mission area with spacetrack (Space Object Identification & Imaging) of geostationary satellities at 0-90E Longitude. It deployed from Vandenberg AFB to Vardo Norway Oct 98-May 99.”
This is supported somewhat by the image in Appendix B of the same collection showing Cosmos 2388 at approximately 35,000 km range, approximately geosynchronous altitude (though Cosmos 2388 itself is in a Molniya orbit).

/ September 11, 2012Allen,
Thanks for your comment.
I completely agree. The P-A-G of GLobus II is probably about one-seventh that of Haystack, so it would take roughly seven times longer to produce a comparable image, but the integration times involved are already quite long, so in many cases that wouldn’t matter much. And thanks for the point about Cosmao 2388. I had seen this in your collection before, but had forgotten where I’d seen it.

/ September 11, 2012Just a P.S., but it’s worth noting that if a satellite is truly geostationary (not just geosynchronous) and three-axis stabilized, range-doppler imaging (aka ISAR) isn’t possible from a fixed site on the Earth’s surface because there isn’t any doppler.
