| 摘 要： | 为了提高舰船排气红外辐射监测水平,提出了一种基于声波法的排气烟羽温度测量和辐射强度计算方法.利用声速与温度的关系,建立排气温度场声学测量模型,通过声波传感器测量的声波传递时间,重建排气烟羽温度分布.利用该温度分布,通过解算红外辐射模型,获取排气红外辐射强度.通过仿真实例对该方法进行了验证,仿真结果表明:基于声波法的温度场重建方法在5%的测量误差水平内具有良好的重建效果,基本解决了舰船排气温度场和辐射强度实时计算的数学模型问题,为进一步开展舰船红外辐射实时监测技术的实船应用奠定了基础.

| Abstract: | To improve the level of the infrared radiation on naval ship,a calculation method for the temperature measurement and radiation intensity of chimney exhaust was presented based on the acoustic theory.According to the relations between velocity of speed and temperature,the acoustic measurement model of the temperature distribution of ship exhaust was established.By measuring the transmition time of the waves with acoustic wave sensor,the infrared temperature distribution of chimney exhaust could be reconstru... |
