Cost-effective Ku-band airborne SAR with Doppler centroid estimation, autofocusing, and indication of moving targets

A Ku-band airborne SAR with Doppler centroid estimation, autofocusing, and indication of moving targets has been recently developed and tested at the Institute of Radio Astronomy of the National Academy of Sciences of Ukraine. This paper describes the setup of this instrument, its main components, and the signal processing technique introduced. Results obtained during the first flight tests are summarized as well
