Robust Method for Solving Rational Function Model

In the past 10 years, the research on the Rational Function Model (RFM) has been a hot spot since the vendor of IKONOS high-resolution remote sensing image bring it into the commercial application. There are many points of RFM for research, but people mainly focus on how to overcom its ill-posed problem, and look for robust methods for solving the RFM. In this paper, new studies on the ill-posed problem of RFM has been done, and a effectively robust method for overcoming the ill-posed problem of RFM is proposed.
