In this paper, the tomography of well LII based on spaceborne P-band SAR is investigated. A mandatory requirement of the proposed approach is that the echoes scattered by LII can be well separated from the SAR echoes scattered from the target on the ground. According to this requirement, the lower pulse repetition frequency (PRF) of SAR is required, which is not permitted by traditional P-band spaceborne...
A novel autofocusing real time TWI algorithm using SAR technique in the presence of wall ambiguities is proposed in this paper. A focusing time factor is introduced to obtain a dynamic image at different focusing time. The choice of the optimal image and the corresponding focusing time can be determined by a maximum entropy criterion. The spectrum Green's function is employed to formulate through...
