摘要：

Tomography SAR (TomoSAR) imaging can distinguish different scatterers in the same pixel using their spatial frequency spectrum difference. Sparse scatterers case located in one pixel can be imaged using high resolution spectral estimation algorithm or compressed sensing (CS) algorithm. For the pixel where the top position of the electric power transmission tower is located, it can be seen this sparse scatterers case. In this paper, TomoSAR imaging methods based on MUSIC algorithm, ESPRIT algorithm and CS algorithm are used to calculate the height of the electric power transmission tower, respectively. TerraSAR-X data is used for experiment. The experimental results demonstrate the ESPRIT algorithm has better accuracy than the other two algorithms for the height estimation of the study electric power transmission tower. Basically, this accuracy can meet the requirement in practical applications.
