摘要
本文从连续叠加(即相当于高次覆盖)的研究出发,导出其叠加特性,给出了由费涅耳积分科纽蜷线求取叠加特征的表达式,由此提出了压制多次波的较简单的参数选择与计算方法。文章指出,在压制多次波方面,单纯靠提高覆盖次数不一定是有益的,更重要的是选择合适的偏移距及排列长度。
This paper proceeds from the study on the continuous stack (analogous to multiple coverage) and the characteristics of stacking is thus derived. An expression to determine the characteristics of stacking thru Fresnel integral or Cornu curve is given. Based on that an easier way to select parameters and a calculus for suppressing mutiples are suggested. Moreover, the paper indicates that it is not likely [to contribute much to suppress multiples just depending on increasing the fold coverage only. What's more important is to try picking the appropriate offset and spread length.
