数字式大气湍流探测仪及其数据可靠性研究

设计了一种新型的数字式大气湍流探测仪。采用偶极子传感器件 ,优化设计了模拟和数字滤波电路 ,提出了综合运用滑动平均和增量处理算法 ,解决了高频信号干扰和突发干扰等问题。仿真和实验结果表明 ,此电路与传统的探空仪电路相比具有高灵敏度、低噪声和数据可靠的优点。

A new pattern of digital atmospheric turbulence detector is designed with the adoption of the dipole sensor device in this paper.The analog and digital filters are also optimized.The MA (Moving Average) and the incremental processing algorithms are provided to give a solution to the problems of the high frequency and gusty interference.Both the simulative and the experimental results show that the performance of our approach is much better than the traditional systems in sensitivity,data reliability and noise level.
