Abstract:
During the last RAMSES bistatic campaign with RAMSES transmitting at X band for a passive receiving radar on a Stemme touring motor-glider, the receiving aircraft have been twice imaged in flight with 40 cm resolution. This successful imaging required advances in both image synthesis algorithm (apparent transmitter trajectory in the target frame is extremely uneven due to target attitude fluctuation) and autofocus algorithm (for retrieving both trajectory and attitude estimation errors).
