| Abstract: | The acoustic scattering of sound hard obstacle in shallow ocean is investigated. The problem can be reduced to a boundary integral equation in which the kernal function is represented in an infinite series. The existence of the wavelet solution to the integral equation is discussed and the kernal is truncated function approximately. The convergent rate of truncation error is O(1/n 3) . This paper approximates the resulting truncation via periodic wavelet,and discusses the estimate of error. |
