通过对干旱地区某地探空资料的分析，拟合出不同季节条件下折射指数随高度变化的拟合公式，利用拟合公式计算了光电跟踪设备使用不同波长跟瞄空间目标时的蒙气差、大气色散和测距修正量。结果表明：(1)在相同视仰角的条件下，冬季的蒙气差修正结果大于其余季节的结果，且大于标准大气的计算结果，而春、夏、秋季的蒙气差小于标准大气的计算结果；(2)春季的0.55μm与1.3μm、3.9μm的大气色散较其余季节的结果为大，对于0.55μm与1.3μm及3.9μm之间的大气色散在视仰角大于55o条件下差别并不明显；(3)不同季节、不同波长测距修正量的变化特点略有不同，其中夏、秋季节特点较为相似，3.9μm测距修正量受季节影响较0.55μm与1.3μm更为明显。所得结果可为该地区光电工程应用提供参考。

Based on the analysis of long-term sounding data in the arid environment, different seasonal fitting formulas on refractive index, which varied with heights, were obtained. The formulas were used to calculate atmospheric refraction, atmospheric dispersion and ranging of space target under the certain condtion by the opto-electronic tracking equipments of different wavelengths. The results show that, for atmospheric refraction, the result of winter is greater than the result obtained by standard atmosphere, and is greater than the results of the remaining three seasons. For atmospheric dispersion, the difference between 0.55μm and 1.3μm, and the difference between 0.55μm and 3.9μm in spring are more than the results of the other seasons. The differences between different wavelengths are small on condition that the elevation is larger than 55o. For ranging correction, the varied characteristics of different wavelengths in different seasons have slight differences, and the characteristics of summer and autumn are similar. The ranging value of 3.9μm is more sensitive than other wavelengths. As a reference, the above results can be provided for certain applications on opto-electronic engineering.
