First Results from the Multibeam Bistatic Beampark Experiments at FGAN

In 2006 the first debris observation campaign in the bistatic beampark mode with FGAN's TIRA L-band radar as transmitter/primary receiver and MPIfR's 100 m Effelsberg radio telescope, which was upgraded by a new multi-beam system, as secondary receiver, was conducted. Due to the properties of this high-sensitive 7-beam receiver new algorithms for the estimation of object parameters such as RCS and trajectory were developed which had to work even for sub-centimeter sized objects. As the new algorithms have already been tested with simulated data and partly validated with real data the focus of this paper is their application on the data gathered during the Multi-beampark experiments in 2006 and 2007 and the validation of the results by comparison with the corresponding TIRA data.
