一种非迭代的声学反演点散射体散射系数方法
A Non-lterativeacoustic Method to Obtain Scattering Coefficients of Multiple Point Scatterers
摘要
Abstract
In the environment of multi-body scattering,a non-iterative acoustic method is proposed in this paper to obtain the scattering coefficients of point scatters.The method takes advantage of anonvector mathematic operation to avoid measuringmulti-static response matrix.Comparing with existing methods,the proposed method is more convenient to operate.To verify the method,two layout environmentsare simulatednumerically and the simulation results of the proposed method are compared with the results of two existing non-iterative methods.The above simulation has taken into account the effect of noise.The result of simulationdemonstrates that:(1) thecondition number of the matrixes that appear in the formulas of the aforementionedthree methods is determined by the layout environment.It is this way that the layout environment affects simulation result;(2)the influence degree of noisedepends on layout environment;(3) the influence degreeof layout environment on the condition number of the matrixesin the above three methodsis different.The performance of the three methods depends on specific layoutenvironment.关键词
