High Power Large Aperture Radar Observations of the Iridium-Kosmos Collision

We present results from two recent beam park radar experiments conducted with the EISCAT UHF radars in February and May 2009 to survey the debris produced by the Iridium-Cosmos satellite collision. The resulting debris is clearly visible in the measurements. The results are compared to a simulated observation produced with the ESA PROOF model. The measurements are found to agree to some extent with the model, but there are still discrepancies between the measurement and the simulation, mainly in the shape of the debris cloud and the total amount of observed debris.
