摘要：
The issue of Direction-Of-Arrival (DOA) estimation in low-angle tracking environment for Very High Frequency (VHF) MIMO radar is investigated in this paper. Under the condition of the reflecting surface height is unknown, an algorithm for the target elevation estimation is proposed. The algorithm is based on the criterion of maximizing the correlation coefficient of target echo and the atoms of a given dictionary, where the dictionary grids can be iteratively refined to estimate the parameters more precisely. The simulation results indicate the effectiveness of the algorithm. © 2016, Science Press. All right reserved.
