A simulation and evaluation system for imaging interferometer

According to the demands of processing imaging interferometer data cubes,which come from the remote satellites,an evaluation system is necessary to estimate the performance of all kinds of processing algorithms.Aiming at the imaging interferometers of the satellites,an estimative method based on normalized cross-correlation coefficient(NCC) for data cube reconstruction quality of imaging interferometer is presented.According to the context of a real imaging spectrometer,a simulation system is built and many simulative tests are done.The experimental results prove that NCC is robust and feasible.
