摘　　要：针对星载的干涉型成像光谱仪提出了一种基于归一化互相关系数的光谱数据立方体重建质量的量化评价方法,并以工程化的要求作为仿真背景条件,建立了一个通用仿真系统。通过仿真,证实了基于归一化互相关系数的成像光谱仪数据立方体重建质量量化评价方法是可行的。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.
