野外次声信号实时测试分析系统的研制

Development of a field real-time analysis and test system for infrasound signals

野外次声信号实时测试分析系统实时采集野外环境下超低频信号(20Hz以下,次声范围)通过计算机的分析、处理,以可视化方式显示出声波的频率和强度,并直观显示结果图形,自动生成曲线,打印最终结果。

Ultralow frequency below 20Hz signals can be collected by a field real-time analysis and test system for infrasound signals. Then a computer analyze and process the data display the visual frequencies and intensities of the waves and print the result as a figure and curve.
