摘要
为解决近程毫米波雷达目标探测过程中产生的回波相位干涉问题, 引入全息技术研究近程目标的毫米波散射特性成像。该方法利用相位补偿因子, 在波数域补偿电磁波的波前球面弯曲, 反演目标的真实几何形状特征。给出了单目标散射特性一维成像的仿真实验, 验证全息成像算法的有效性。对有无相位补偿情况下的多目标散射特性一维成像进行比较, 结果表明该方法大大提高了成像精度。
Abstract
In order to deal with the problem of echo phase interference of short-range MMW radar in target detection,the holographic technology was introduced to study short-range target MMW scattering imaging. The method used phase compensation factor for compensating the spherical wave front of electromagnetic wave. Thus the true geometric characteristic of the target geometry was obtained. Simulation was made for one-dimensional scattering imaging of single target. It verified the effectiveness of the holographic imaging algorithm. The one-dimensional scattering imaging of multi-target with phase compensation was compared with the one without compensation, and the result showed that the method with compensation can improve the imaging accuracy greatly.
