This article introduces a new method for localizing high-speed moving sources with a microphone array followed by a chirplet transform. A well-adapted chirplet is constructed and the accuracy of the method is studied within a general case. Simulations and real data from the high-speed train (Train a Grande Vitesse), are compared with the current deDopplerization method.
