航空推扫成像时，由载机的姿态变化产生的像移是影响光学成像质量的主要因素之一，可由稳定平台进行补偿。基于某机载成像光谱仪系统，首先利用齐次坐标变换法建立像移速度矢量的精确计算模型，分析了成像质量对飞行姿态精度的要求，从而选定稳定平台参数。接着，分析了姿态补偿残差对成像质量的影响，得出引起的相对像移速度偏差仅为10-1，为后续光谱定标和几何校正提供了参考。再次，研究了给定成像要求的飞行参数指标的分配问题，进行了像移速度误差分析。最后，开展了飞行成像试验。结果表明所选的PAV30稳定平台能够确保成像期间的姿态稳定，验证了上述分析正确合理。所提出的方法简单，易于实现，具有一定的工程应用价值。

The shift generated from aircraft attitude change was one of the main factors affecting the optical imaging quality in aerial push-broom imaging,which could be compensated by stable platform. In this article,based on an particularly airborne imaging spectrometer system,firstly the precise image motion velocity model was established by the homogeneous coordinate transformation method, and the flight attitude accuracy required by the imaging quality was analyzed, thus the parameters of stable platform could be choosed correctly. Then the influence of the residual of compensation of attitude on the imaging quality was analyzed, obtaining the relative shift speed deviation was only 10-1, which providing references for the following spectral calibration and geometric correction. Again, to study the distribution of flight parameters of a given imaging requirement, the error analysis was carried out. Finally, the flight imaging test was carried out. The result showed that the selected PAV30 stable platform could ensure the demand of stability during imaging, which verifying the above analysis was correct and reasonable. The proposed method was simple and easy to implement, having a certain value in engineering.
