| 摘 要： | 基于脉冲探地雷达的后向投影（back-projection，BP）成像算法在处理大宗数据时由于运算量大而使得计算效率较低。文中在传统BP算法的基础上提出了一种快速后向投影（fast back-projection，FBP）成像算法，并以单个点目标和多个点目标的成像为例，将该算法应用于脉冲探地雷达的成像，其计算效率较传统的BP算法有显著提高，而且理论推导和仿真结果均表明，FBP算法的成像质量与传统BP算法相近，从而得出了FBP算法的优越性。

| Abstract: | GPR(Ground Penetrating Radar) is one of the highest resolution and most efficiency underground survey equipments.The application of the back-projection(BP) algorithm for ImpGPR(Impulse GPR) imaging is restricted due to its great computation load when there are a great number of data.Based on the research on the traditional back-projection algorithm,a fast back-projection algorithm for ImpGPR is presented in this paper.Taking spot target and multi-spot target for example,the computation efficiency of the alg... |
