摘要

The simulation of remote sensing images is a useful tool for a variety of tasks, such as the definition of future Earth Observation systems, the optimization and evaluation of instrument specifications, especially for a new type sensor, and the development and validation of data processing algorithms. A scene simulator for optical hyperspectral data from 'HJ1A-HSI' is described in this paper. 'HJ1A-HSI' was carried on the Chinese small satellite HJ-1A, which was successfully launched on September 6th, 2008. Different from common hyperspectral sensor, 'HJ1A-HSF belongs to the spatial imaging Fourier Transform spectrometer (IFTS). In contrast to the high-speed development of spatial IFTS, the corresponding image simulator is still at the starting stage and the simulation data is very ideal in most cases. To simulate more actual data, a simulation system is proposed in this paper, based on the analysis of spatial IFTS principle. This system puts emphasis on simulating the effects of typical artifacts, and consists of four parts: the calculation of input parameter, the radiance computation for one beam before interfered, the simulation of effects of typical artifacts and the interferogram acquisition. The methodology applied to the complete scene simulation and some sample results are presented and analyzed in this paper.
