摘要：
Multi-channel SAR can reconstruct the 3-D surface of the observed scene with its resolution power in the elevation. However, with limited baseline length, most methods suffer from limited precision and significant miss rates. In view of this situation, a new 3-D reconstruction method using terrain stagnation point based division is proposed. Firstly, 3-D distribution is obtained using tomography; secondly, stagnation point position and division are conducted to separate the layover; then 3-D reconstruction is conducted using interferometry. This method combines the resolving power of multi-channel SAR and high precision of interferometry. Therefore, reconstruction results with higher precision and greater stability are achieved. The effectiveness of the method is validated using experiments with simulated data. ©, 2015, Science Press. All right reserved.
