| 摘 要： | 在中场区通过对相位弯曲补偿进行微波成像,能大大降低对测试距离的要求,本文依据干涉逆合成孔径雷达成像(InSAR)原理,提出中场区滤波-逆投影三维成像算法,在获得目标散射点二维分布和强度信息的同时,还能得到其高度信息,实现中场区目标的三维成像。仿真和实验结果表明算法的有效性。

| Abstract: | The middle-field InSAR imaging by mending curved phase front is as same as the far-field imaging,but can save distance of measurement greatly,with great engineering meanings.In this paper,middle-field CT 3-D imaging algorithm is put forward according to interfere systhetic aperture radar(inSAR) theory.Not only 2-D dictribution of scattering centers and their amplitude information are aquired,but also their height are gotten.The simulink and experiment result proved that the algorithm is efficitive. |
