Wide swath SAR imaging with pulse-phase-codes
摘要
Abstract
For traditional monostatic Synthetic Aperture Radar (SAR) , the wide swath imaging and cross-range resolution are mutually limited- However, conventional approaches are always to make a trade-off between the both. To overcome the problem, a novel algorithm for resolving range ambiguity is proposed by using the technique of Pulse-phase-codes, in which wide swath imaging could be achieved without the loss of cross-range resolution. In the scheme, the geometric model and linear equation are constructed with modulated initial phases to realize range ambiguity. Meanwhile, high quality of SAR imaging could also be achieved. Besides, the proposed algorithm has the advantages of low system complexity and easy implementation. Experimental results by using simulated data confirm the validation of the proposal.关键词
