摘要

本文将近年来自主开发的毫米波成像(MMWI)算法GHI-LFM，即基于线性调频(LFM)的通用全息成像(HI)算法，利用相干因子(CF)进一步改进，称为GHI-LFM-CF。该方法可以抑制k空间中的吉布效应，得到非常干净的背景。通过对基准目标的合成和实验数据进行成像，验证了其优越的性能。

Improved GHI - LFM Algorithm Based on Coherence Factor

In this paper, the recently indigenously developed millimeter-wave imaging (MMWI) algoritthm GHI-LFM, namely general holographic imaging (HI) algorithm based on linear frequency modulation (LFM), is further improved by using coherence factor (CF), called GHI-LFM-CF. The new method can suppress the Gibb's effect in k-space, resulting in very clean background. The superior performance is validated by imaging using both synthetic and experimental data of benchmark objects.
