Technologies for 3-D CT of gas temperature and flow distributions based on the MAP estimation with local iterations which is referring acoustic time-of-flight through non-linear observation process is proposed. The technologies are featured signal processor with pre-whitener and complex absolute detection for received signal to cope with unknown and non-linear phase shift. The proposed technologies has provided the standard deviation of the identified time-of flight was one tenth as that of the previous technique. The technologies has been shown to effectively estimate the distributions in large scale chambers and outdoor environments.

提出了一种基于局部迭代MAP估计的气体温度和流量三维CT技术，该技术通过非线性观测过程参考声学飞行时间。这些技术的特点是信号处理器与预白化和复杂的绝对检测接收信号，以科普未知和非线性相移。所提出的技术提供了识别的飞行时间的标准偏差是以前的技术的十分之一。该技术已被证明可以有效地估计大规模室内和室外环境中的分布。
