空中目标红外辐射强度计算通用模型及其应用
|
摘要
提出了一种适用于空中扩展目标和小目标红外辐射强度计算的通用模型,该模型消除了对环境温度依赖较大的背景偏置的影响,可有效提升外场复杂多变环境条件下航空目标红外辐射特性测量结果的精度。结合某型航空目标动态红外特性测试数据,探讨了小目标红外辐射强度的计算问题,结果表明:对于中波红外小目标,大气表观辐射强度对总辐射强度的贡献可以忽略,可以采用简化模型计算总辐射强度,但对于长波小目标红外辐射,简化模型不再适用。对红外小目标和扩展目标的外场动态测试数据分别进行了处理,并与理论结果作比对验证,结果验证了模型的正确性。
A general model for calculating the infrared-radiation intensity of extended aerial targets and small infrared targets is proposed. The model eliminates the influence of background bias, which depends heavily on ambient temperature, and can effectively improve the measurement accuracy of infrared-radiation characteristics of aerial targets in complex and changeable environments. The calculation of small-target infrared radiation intensity is discussed based on the characteristics of dynamic infrared test data of a type of aerial target. The results show that the contribution of the apparently atmospheric radiation intensity to the total radiation intensity is negligible for small medium-wave infrared targets. A simplified model used to calculate total radiation intensity is presented, but it is not applicable for small-target long-wave infrared radiation. The dynamic small-target infrared test data and the extended-target data are processed and compared with theoretical results, and the results verify the correctness of the model.
