| Summary: | Soil moisture is one of the critical parameters to be considered in civil, geological and agricultural works. Currently, destructive method such as coring technique is used to retrieve the soil information but it is time consuming and expensive, but it is still considered as accurate method to obtain the soil information as compared to other remote-sensing methods. Destructive methods have its own drawbacks including its cost and process time, and the process destroys the ground structure that could give long term effect on the environment. To overcome the obstacles of destructive methods, non-contact and non-destructive tests (NDT) methods are introduced. Various NDT methods are investigated for this application such as microwave method and near-field method. One of the most notable NDT method for soil investigation is radar technology. Ground penetrating radar (GPR) as a subset of radar technology is identified to be the pioneer in soil investigations. However many assumptions need to be made to obtain soil information in non-destructive manner but research is on-going to tackle this matter. |
