摘要
从克希霍夫积分偏移和绕射扫描偏移的基本原理出发 ,通过对探地雷达 ( GPR)实测资料进行对比处理 ,说明偏移处理能够使地下及空中绕射归位收敛 ,用改变偏移速度的方法识别空中绕射有特殊效果 。
This paper begins with the basic principles of Kirchhoff migration and diffraction scan migration,then compares the processing results of the practical GPR data with these two migration methods.It is illustrated that migration can make diffraction wave convergent and the diffraction from air can be recognized effectively with migration method by changing the migration velocity,which can provide the foundation for interpretation,thus improving precision of interpretation of GPR profiles.
