However a question arises:"Suppose there are some errors in the nearfield measurement on the boundary, what will be the errors in the estimation in the farfield by these source methods?" A numerical simulation is performed by setting possible errors in the nearfield measurement, then the errors in the farfield are evaluated. The results indicate that the source methods give fair estimations in the farfield, even with possible errors in the nearfield measurement. Besides, in order to capture analytical characteristics of source methods,we will discuss the influence parameters of similar source method(SSM) in thearticle.
