The real-time gpr signals preprocessing algorithm based on LWT in high scan rate

Abstract

In this work, we use DSP mechanism for real-time Ground Penetrating Radar (GPR)data preprocessing assess in high scan-rate scenarios. The lifting wavelet transform-based algorithm takes the advantages of efficient computation and memory reduction and is a suitable solution for DSP real-time implementation. In addition, the parallel operations technique on DSP memory is applied to enhance the system efficiency. Such that we realize a 3-level pipeline data structure which can significantly release the signal preprocessing time from the data collecting and data display time etc. The experimental results demonstrate the effectiveness of the developed scheme for real-time GPR data processing.
