提出了一种三维（3D）双基地逆合成孔径雷达（ISAR）成像方法。该方法利用干涉测量技术，从技术上讲，通过估计三维笛卡尔空间中的散射中心位置来产生三维目标重建。所提出的方法利用ISAR/干涉测量相结合的技术，也允许ISAR成像平面的方向估计。讨论了十字形和l形天线配置，并详细分析了水平方向和垂直方向基线长度对散射体位置估计的影响。最后，通过数值仿真对该方法的性能进行了评价。
A three-dimensional (3D) bistatic inverse synthetic aperture radar (ISAR) imaging method is proposed in this paper. The proposed method makes use of interferometry and technically speaking, produces a 3D target reconstruction by estimating a scattering center position in 3D Cartesian space. The proposed method makes use of a combined ISAR/interferometry technique that also allows the ISAR image plane to orientation to be estimated. Cross- or L-shaped antenna configurations are discussed, and the effects of the baseline length along the horizontal and vertical direction on the scatterer's position estimation are analyzed in detail. Finally, numerical simulations are used to evaluate the proposed method's performance.
