摘要
提高分辨率是探地雷达(GPR)研究中的一个难题，为了获得深埋目标的清晰成像，迫切需要提高分辨率。探地雷达已被认为是一种非常成功的技术，用于各种隐蔽目标的调查和探测。鉴于MUSIC (Multiple Signal Classification，多信号分类)算法的优越性，本文对其应用的可能性进行了探讨。此外，利用传统的快速傅立叶变换(FFT)获得更高精度的接收信号电平。首次提出了MUSIC和逆FFT (Inverse FFT)时域响应的组合处理方法(CPM)，以获得高分辨率、高精度的接收信号电平。仿真和实验结果表明，与其他传统的信号处理方法相比，该方法具有高分辨率和高精度的接收信号电平。关键词:地下雷达，FFT, MUSIC算法，超分辨率
Application possibilities of super-resolution technique for GPR imaging
ABSTRACT Improvement of resolution is the challenging issue in Ground Penetrating Radar (GPR) and that is greatly desired to increase in order to get the clear imaging of very closely buried targets. GPR has been approved as very successful technology for various kinds of investigations & detection of buried targets. In this paper, the application possibility of super resolution technique MUSIC (Multiple Signal Classification) algorithm is examined because of its superior results. Moreover, the conventional FFT (Fast Fourier Transform) has been utilized to get higher precision receiving signal level. Combined Processing Method (CPM) oftime domain response of MUSIC and IFFT (Inverse FFT) has been proposed for the first time to get high resolution and high precision receiving signal level. Simulation and experiment result show that the proposed method has high resolution and high precision receiving signal level than other conventional signal processing approach. Key words: Subsurface radar, FFT, MUSIC Algorithm, Super Resolution
