In this work the authors present GPR results of the monitoring of an organic target decomposition. The experiment consists in use a buried pig (Sus scrofa) as an organic target, which simulates a human body. The pig was buried at the University of São Paulo campus located in Pirassununga city (São Paulo State) in December, 2012 and has been surveyed periodically with the GPR method. The objective is to evaluate the effects of its decomposition on the GPR reflection data. The results show that the anomaly caused by the body as better viewed in the 270MHz radargrams, while depth slices made with 900MHz data were better to identify the trench borders. The research is still in progess, and the results are important for understand the use of GPR method in searching for human remains.
