Experimentos em Laboratório (1 GHz) e Trabalhos de Campo (200 MHz) com GPR Usando Corpos arenosos para Avaliar a Influência da água e de Hidrocarbonetos na Velocidade e na Amplitude da Onda Eletromagnética

We analyse GPR measurements (1 GHz) which were carried out on a well sorted, clean sand in a laboratory experimental site and we also executed AVO field experiments, both using TE and TM- mode configurations,. The AVO works were conducted on a sand dune field around the Lagoa do Abaeté (Salvador, Brazil).
