摘要
讨论声散射理论中的透射问题和逆散射问题中的远场谱及其性质,证明了远场谱F(x,k;a)满足恒等式F(x,k;a)=F(-a,k;-x). 另得到了透射问题的Herglotz波函数的核函数g(x)
This paper discusses the problem about the far field patterns of transmission in scattering theory for acoustic waves. The far patterns F(x,k;α) satisfy the following equation: F(x,K;α) =F(-α,k;-x).
The relation between the far pattern and the kernal function g(x) of the Herglotz wave function of the transmission in scattering theory for acoustic waves is obtained.
