위성 SAR 기만 재밍을 위한 RLSE 기반 SAR 파라미터 추정 기법.

As numerous synthetic aperture radar (SAR) satellites have been launched to secure surveillance and reconnaissance capabilities, considerable research has focused on SAR jamming methods. In particular, methods that utilize the received SAR signals for deceptive jamming have drawn increasing attention. However, because these methods perform deceptive jamming after the SAR signal is received, they cannot create a false target ahead of the jammer along the range axis. Accordingly, as part of the research on deceptive jamming methods to overcome this limitation, this study aims to estimate the transmission time of the next SAR signal and the center frequency in real time from the received SAR signal. The proposed method precisely estimates these parameters using pulse compression and recursive least squares estimation, and the estimation results are confirmed through simulations.
