3D ISAR Imaging Based on MIMO Radar Array

摘要：

In 3-D ISAR imaging,the separation of scatterers which have same Range-Doppler location is a key problem.In this paper,we propose to use a MIMO radar array,which is located in the z-axis direction,to measure the positions of scatterers of a synthesis scatterer. The x- andy-coordinates of scatters are obtained from ISAR image directly. The z-coordinates are reconstructed by the spatial frequencies of scatterers in each synthesis scatterer based on the MIMO radar array. The simulation results show that the proposed method is effective for 3-D image reconstruction.
