解决反演运算稳定性必须在运算前对信号进行预处理.本文提出时域自适应迭代求层系冲激响应的处理方法,有效地减小由于预处理引起的误差.反演模拟结果与取样实测结果相当符合.
Abstract: For enhancing the stability of inverse algorithms, signal processing has to be done before doing inverse computation. An adaptive iteration method has been propose in this paper to search the response of model before doing the inverse computation. This method decreases effectively the error cause by the signal processing. The result of the model inverse experiment agrees with the measurement of sample in the lab very well.
