Otimização de perfis de reflexão GPR sobre manilhas de concreto e tubulações de PVC instalados no sítio controlado de geofísica rasa do IAG-USP

Abstract: RESUMO. Nesta pesquisa são apresentados resultados de perfis de reflexão GPR realizados sobre duas linhas instaladas no campo de provas do IAG-USP ou Sítio Controlado de Geofísica Rasa do IAG-USP, visandoà obtenção de parâmetrosótimos de campo para melhorar a caracterização de interferências normalmente encontradas no ambiente de grandes centros urbanos. Uma linha de estudosé caracterizada por manilhas de concreto vazias de diferentes diâmetros e a outraé caracterizada por tubulações de PVC com 4 de diâmetro (… Show more

“…O Set Time Zero objetiva eliminar o efeito da onda direta e realiza a correção do tempo zero (Furtado, 2009). Este passo do processamento faz com que o tempo zero corresponda à superfície em que a antena foi posicionada, o que faz com que todos os alvos e estruturas identificados em subsuperfície tenham seus valores de tempo duplo corretamente ajustados (Lima, 2006).…”
