| 摘 要： | 蒸发波导高度是表征蒸发波导强度的重要参数。分析了基于PJ模型的蒸发波导探测系统对气海温差、相对湿度、风速以及传感器误差敏感性。根据测试情况,分析了影响蒸发波导高度的敏感因子。综合考虑传感器的测量误差,蒸发波导高度诊断的相对误差在稳定条件、不稳定条件以及中性条件下分别为14.3%、4.22%、8.05%。求解了蒸发波导中电磁波传输的抛物型方程,并运用雷达理论计算了蒸发波导环境中的最大探测距离。

| Abstract: | The height of evaporation duct is an important parameter to represent the duct intensity.The sensitivity of evaporation duct detection system based on Paulus-Jeskes(PJ)model is analysed to the air-sea temperature difference(ASTD)and relative humity and wind speed and sensor errors.Based on the test results,the sensitivity factors affecting the height of the evaporation duct were analyzed.Considering the sensor errors all,the relative diagnostic error of the evaporation duct height are 14.3%、4.22%、8.05%respectively in the stable condition and unstable condition and neutral condition.The parabolic equation of electromagnetic wave propagation in the evaporation duct is solved,and the maximum detection distance in the evaporating duct environment is calculated by radar theory. |
