摘要
将自适应聚焦束拓展到弹性介质中,基于弹性格林函数的构建,结合自适应聚焦束的优势,并考虑黏滞性对高斯束的影响,发展基于衰减补偿的多分量自适应聚焦束偏移方法.模型测试验证了本文方法的正确性和适应性.结果表明,新方法能够适应强横向速度变化,压制噪音对成像结果造成的影响,使成像剖面更加干净清晰.
Abstract
This paper extends the adaptive focused beam technique to elastic media.By constructing elastic Green̍s function and incorporating the advantages of adaptive focused beams while accounting for the influence of viscosity on Gaussian beams,we develop a multi-component adaptive focused beam migration method based on attenuation compensation.Model tests verify the correctness and adaptability of this method,demonstrating its ability to handle strong lateral velocity varia-tions,reduce noise impact on imaging results,and produce cleaner,clearer images.
