Abstract
En 中文
• Proposes a wave packet separation algorithm based on sparse point array. • A practical structural defect detection workflow is established. • An optimal receiving distance calculation method is proposed. • Localization and relative size identification of rail defects is achieved. • Separation of advancing and reflected waves of a multimodal wave packet.
