提出了一种改进的反投影成像算法用于地下目标检测。首先,分析了传统反投影成像中各时延曲线上散射数据的特征;其次,对每个焦点设计一个权重因子,提出一种改进的反投影成像算法;第三,对改进后的成像算法进行了仿真。仿真数据和真实探地雷达数据的成像结果表明了该成像算法的有效性。
An improved back projection imaging algorithm for subsurface target detection is presented in this paper. Firstly, the characteristic of the scattering data at each time-delay curve in the traditional back projection imaging procedure is analyzed. Secondly, a weight factor is designed for each focal point and an improved back projection imaging algorithm is presented. Thirdly, the simulation of the improved imaging algorithm is processed. The imaging results of both the simulation data and the real ground penetrating radar data show the effectiveness of this imaging algorithm.
