地下目标极点提取与实验研究

EXTRACTING POLES OF BURIED TARGETS AND EXPERIMENTAL RESEARCH

本文给出了一种改进的提取目标极点方法,并指出在有噪声时特征值方法确定极点数目更准确,证明了特征值法的逼近误差总是小于经典方法的,最后进行了若干种埋地目标极点提取试验。得出几点很有意义的结论。

An advanced method to extract the poles of a buried object is presented. It is proved that approaching error using eigenvalue method is always less than the errors using any one of the classical methods. Experiments for extracting the poles from several targets have been done. Finally we get some significant conclusions.
