【Abstract】 Continuous-wave synthetic aperture radar research work is presented in this paper. Based on time-frequency capacity analysis and between-pulse phase modulating mehtod, this paper gives a theory of suppressing range ambiguity and an implement technique of contiguous-wave SAR, and also gives analysis of relevant problems and results of simulation. The simulation results show the principle of the theory is correct and the technology is feasible. The method can provide flexible scan cycle which brings great freedom in SAR system designing.更多还原
