摘要

本文介绍了移动声源分析的第一步。时间频率和时间尺度工具用于表征固定麦克风接收到的信号。它允许人们改进定位方法。在正弦源的情况下进行了仿真。在高速列车(TGV)上进行了已知源固定的实验。然后，对某高速列车在实际工况下经过的信号进行了分析。

High-speed moving sources analysis

This article describes the first step of moving acoustic sources analysis. Time-frequency and time-scale tools are used to characterize the signal received on a fixed microphone. It permits one to improve localisation methods. Simulations are presented in case of a sinusoidal source. An experiment with a known source fixed on a high speed train (TGV) is carried out. Then, the signal of a TGV coming by in real operating conditions is analysed.
