PUMA applied to time delay estimation for processing GPR data over debonded pavement structures

Résumé

In this paper, principal-singular-vector utilization for modal analysis (PUMA) was adaptedto perform time delay estimation on ground-penetrating radar (GPR) data by taking into accountthe shape of the transmitted GPR signal. The super-resolution capability of PUMA was used toseparate overlapping backscattered echoes from a layered pavement structure with some embeddeddebondings. The well-known root-MUSIC algorithm was selected as a benchmark for performanceassessment. The simulation results showed that the proposed PUMA performs very well, especiallyin the case where the sources are totally coherent, and it requires much less computational time thanthe root-MUSIC algorithm.
