摘要
针对分层媒质参数重构问题,提出了一种分层电介质参数重构的新方法,将矩阵束法成功地应用于分层电介质频域反射信号的分解,并利用矩阵束原理重构出分层电介质的参数。在重构过程中,分别考虑了不含噪声和含噪声两种情况。由于矩阵束法中采用最小二乘算法避免了迭代计算,与已有其它算法相比,具有更高的抗噪声性能、稳定性也更高。仿真结果表明,所提出的媒质重构新方法具有实时、高效等特点,为分层媒质参数重构提供了一条新的途径。
The reconstruction of stratified permittivity profiles is one of the important inverse scattering problems. A new reconstruction technique is proposed based on the frequency domain matrix pencil method. During the reconstruction process, two situations with and without noise are considered. The simulated results show that the new method proposed here has advantages of stability, high efficiency and real-time, which provides a new way to reconstruct the stratified permittivity profiles.
