The ocean surface topography usually varies only a few centimeters among hundreds of kilometers spatially, therefore, the altimetric accuracy of an Imaging Radar Altimeter (IRA) needs to be on centimeter-level for ocean altimetry. The baseline of an IRA from satellite formation is flexible, which can reach to thousands of meters while maintain higher stability than an IRA from single platform. The large baseline can increase the altimetric accuracy with great potential, however, the signal decorrelation deteriorates as well as the baseline increases, prevents the accuracy from further being improved as the baseline reaches to a certain length. The baseline decorrelation can be compensated by a carrier frequency shift, however still left the volumetric decorrelation associated to wave height variation deteriorates with the increasing baseline. In this paper, the upper limit accuracy of an IRA system determined by the wave volumetric decorrelation was deduced, the parameters of the IRA system were optimized accordingly. The simulation results indicates that the altimetric accuracy of the proposed IRA system can reach to sub-centimeter level on a 1km resolution gird, with the baseline length ranges from 650~1000m.
