| 摘 要： | 卫星平台振动导致色散型成像光谱仪在曝光过程中与地物产生相对运动,从而严重地影响了光谱数据质量.本文以PHI为色散型光谱仪模型,研究计算了俯仰角、侧滚角、偏航角以及三角综合按照卫星振动信号和不同振幅的谐波振动对光谱数据的空间图像和光谱的影响程度,并且仿真出了各种振动下的畸变光谱数据立方体,得到卫星平台振动造成光谱数据畸...

| Abstract: | atellite platform vibrations make dispersive imaging spectrometer and objects generate relative movement in exposuretime,which seriously affects the quality of spectral data.PHI was made as the model of dispersive spectrometer,the impact ofpitch,roll,yaw and three-axis vibrations on spectral data were studied chiefly,and distorted spectral data cubes under variousvibrations were simulated,then the general law of distortion spectral cube caused by satellite platform vibration was gained.The results show that... |
