摘　　要：针对复阻抗式结冰探测技术中急需解决环境温度影响的问题,分析了冰的驰豫极化过程,并结合实验数据求解出了冰的复介电常数与温度的关系,提出了一种复阻抗式结冰探测技术下的温度补偿方法。为了提高温度补偿准确性,降低标定工作量,通过对驰豫极化理论的分析及温度漂移模型的构建,实现了准确可靠的温度测量补偿方法,该方法减小了结冰厚度对温度补偿效果的影响,极大降低了复阻抗参数温度补偿工作的复杂度。结冰实验结果表明,本文提出的温度补偿方法在-24℃~-3℃的环境温度条件下,可将温度漂移对测量结果的影响减少80%以上,有望显著提高复阻抗式结冰探测器的温度补偿准确性及标定效率,具有一定的工程应用价值。Aiming at the urgent need of solving environmental temperature influence in the complex impedance icing detection,analyzes the relaxation polarization process of ice,combines the experimental data to obtain the relationship between the complex permittivity and temperature of ice,and proposes a temperature compensation method for complex impedance icing detection.In order to improve the accuracy of temperature compensation and reduce the workload of calibration,implements an accurate and reliable temperature measurement compensation method through the analysis of the relaxation polarization theory and the construction of a temperature drift model.It weakens the influence of icing thickness on temperature compensation,and greatly reduces the complexity of temperature compensation for complex impedance parameters.Icing experiment results show that the proposed method can reduce the influence of temperature drift on the measurement results by more than 80%under ambient temperature of-24℃to-3℃,which significantly improves the compensation accuracy and calibration efficiency.The proposed method has certain value of engineering application.
