Abstract
Various types of "second generation" SAR with multi-sensing mode, replacing "classic" SAR like one on Seasat have been proposed to meet many user requirements.
In this paper, a design method of SAR with variable sensor system parameters utilizing unfocused SAR principal positively is proposed to make variable off-nadir angle observation with constant high spatial resolution in costant swath width, available with one SAR system. And inherent technological problem on the ambiguity of SAR with variable off-nadir angle are discussed.
