摘　　要：建立了空间热流的计算模型和空间气球与包络球的温度场计算模型;然后建立了两者红外辐射强度空间分布的计算模型;最后计算了空间气球与包络球在白天和夜间两种条件下的温度场分布,并详细分析了两者温度场分布以及3~6?m和6~16?m两个波段内红外辐射特性的差异。结果表明包络球与气球在飞行过程中的红外辐射特征极为相似,采用包络球的方式可以很好地对空间目标进行伪装。本研究结论对于空间目标的红外伪装与探测具有参考价值。In this paper,the space heat flux and the temperature field calculation models of envelope and spatial balloons were established.In addition,the models of their infrared radiation intensities were constructed.Finally,temperature distributions of envelope and spatial balloons were calculated and the differences in temperature distributions and infrared radiation features in the 3-6?m and 6-16?m bands were analyzed.The infrared radiation features of both bands were similar and the envelope balloon was found to be a suitable camouflage method for spatial targets.The research results of this paper have referential value for infrared camouflage and the detection of spatial targets.
