摘要 本文针对探地雷达系统(GPR)时延估计(TDE)中使用的一种新型Toeplitz结构协方差矩阵算法进行了研究,并在不同BΔτ值条件下对这种新算法进行了计算机仿真。通过对仿真结果的分析,界定了该算法的适用范围。对实际情况下算法的选用具有一定的指导意义。 This paper deals with a new Toeplitz structured covariance matrix technique for Time Delay Estimation (TDE) in Ground Penetrating Radar (GPR) system. After testing the performance of this technique under different BAr products, the range of application for this new technique in this area is defined, and a guide for how to choose algorithms in actual cases is given.
