An important issue of ground-penetrating radar (GPR) signals analysis is de-noising that is the guarantee of acquiring good detecting effect. The paper illustrates a successful application of digital single processor (DSP) based on wavelet shrinkage algorithm. In order to realize real-time GPR signals analysis, some key issues are discussed such as the realization of fast wavelet transformation, the selection of CPU chip and the optimization of data movement. Experimental results show that the DSP based application not only basically meets the real-time requirement of GPR signals analysis, but also assures the quality of the GPR signals analysis.

In order to realize real-time GPR signal analysis, some key issues are discussed such as the realization of fast wavelet transformation, the selection of CPU chip and the optimization of data movement. Experimental results show that the DSP based application not only substantially meets the real-time requirement of GPR signals analysis, but also assures the quality of the GPR signals analysis.
