Chapters

Here we present a Ground Penetrating Radar (GPR) system based on a ground-coupled, densely populated antenna array for monitoring the dynamic process of subsurface water infiltration. A time-lapse radar image of the infiltration process allowed estimating the depth of the wetting front during the course of the infiltration process.

Inlet For Water Drainage Ensure That The Tubes Are Securely Placed In The Soil To Prevent Any Movement During The Experiment Position The Array Antenna Ground Penetrating Radar System Near The Infiltration Test Site Ensure That It Is Properly Set Up And Calibrated For Data Collection The Radar System Should Be Connected To A Computer Or Data Acquisition Device For Real time Data Recording Start The Infiltration Test By Opening The Valve To Allow Water To Flow Into The Tubes Monitor The Water Infiltration Process Closely And Record The Data Collected By The Radar System At Regular Intervals As Water Infiltrates Into The Soil

The Radar System Will Capture Changes In Subsurface Properties

Such As Moisture Content And Soil Structure These Changes Will Be Reflected In The Time lapse Multi offset Gathers Collected By The Array Antenna Continue Collecting Data Throughout The Infiltration Process Until A Sufficient Amount Of Information Has Been Gathered This Data Can Then Be A
