| Abstract: | Based on the signal model of SAR with linear array antennas, a three-dimensional imaging algorithm using elevation angle compression principle is proposed. Range cell migration correction (RCMC) is incorporated in the three-dimensional imaging algorithm. The three-dimensional imaging principle of SAR with linear array antennas is analyzed from the point of view of elevation angle compression principle. The simulation results support the signal model and three-dimensional imaging algorithm. |
