二维近程微波全息成像技术已被考虑应用于人体安检、医疗成像、隐匿武器检测等，该技术采集前、后向散射数据，入射场完全由测量或模拟直接获得，成像质量和分辨率相比近程毫米波全息成像技术有一定提高。但该技术现阶段还没有成像系统，仍处于起步阶段。对于该技术的算法实现，给出了一套利用任意复杂电磁计算（feldberechnung bei korpern mit beliebiger oberflache，FEKO）软件模拟目标散射波和入射场，并对获取数据进行网格化方法处理，最终将处理后数据重构目标图像的实现方案。在此基础上，证明了真实的入射场和前向散射数据对成像效果影响显著，同时分析了不同扫描孔径、天线位置、复杂物体的成像效果，并给出相应结论，为实际应用提供参考数据。

Two-dimensional short-range microwave holographic imaging technology has been considered to be applied to human security checks,medical imaging,concealed weapons detection,and so on.This technology collects back-scattered and forward-scattered data,and the incident fields are obtained entirely by either meas-urement or simulation directly.The imaging quality and resolution compared with the short-range millimeter wave holography imaging technology have certainly been improved.But this technology has yet no imaging sys-tem,and are still in its infancy.A set of program is proposed to realize the algorithms of the technology which employ feldberechnung bei korpern mit beliebiger oberflache (FEKO)to simulate scattering waves and incident fields of the target,and then uses the grid method to process the gets data.Finally,the processed data are used to reconstruct the target image.On this basis,it is proved that the true incident filed and forward-scattered data significantly affect the imaging results.Simultaneously,the effectiveness of target images got by changing the scan antenna aperture size,location and images of complicated target object are analyzed,and the corresponding conclusions are given,providing reference for practical applications.
