Evaluation the resolution of : [GPR radargram] influenced by [LNAPL] based different type of frequency / Abdullah Hadi Shabri

The contaminated o f subsoil usually happens because o f the leakage of hydrocarbon from buried tanks or pipe. Hydrocarbons usually come in the form of liquids and gaseous with different saturation. These hydrocarbons will interfere with electromagnetic wave from GPR and give an effect to GPR dat...
