旋转目标干涉逆合成孔径三维成像技术

本文根据旋转目标微波成像原理，导出了采用干涉逆合成孔径（ＩＮＩＳＡＲ）处理获取第三维高程信息的旋转目标ＩＮＩＳＡＲ三维成像技术，这种技术通过鉴别由俯爷角微小差异的两副天线分别获取的两幅相位相干的二维图像对应获射中心的相位变化来确定散射中心在竖直维的位置；散射中心的横坐标，纵坐标及幅度由一幅二维图像给出，模拟计算与飞机模型实验测量均得到满意结果。

INISAR 3-D Imaging Technique for Rotating Targets

Based on the principle of microwave imaging of the rotating targets,an INlSAR (ISAR Interferometry) 3-Dimaging technique of rotating targets is daseribed in this paper. The vertical position of scattering centers are given by comparing their phase difference fo two phase coherent 2-D images which are obtained by using two antennas with a little change in pitch angle. The doWn-range and cmerange opition and amPlitude of anttering centers of the 3-D irnage are given by one 2-D image .The The simulated and measured results are all satisfactory.
