System and method of underground water detection

A system for determining underground water content, comprising:

• a processor;
• and
• a non-transitory computer readable medium having stored thereon computer-executable instructions which when executed by the processor cause the processor to:
• receive a first scan of an area at a first polarization, the first scan including first L band microwave reflections from the area;
• receive a second scan of the area at a second polarization, the second scan including second L band microwave reflections from the area, the first and second scans being from a first sensor for detecting L band microwave radiation reflections attached to an object located at least 50 meters above the area;
• filter electromagnetic noise from the first scan using the second scan;
• create a water roughness map based on typical roughness values of various types of water sources and the filtered first scan;
• identify a first type of water sources using the water roughness map and the filtered first scan;
• and
• calculate the water content at locations in the area based on the identified first type of water sources.

A method of remote detection of underground liquid content, comprising:

• receiving at least two scans of an area, each of the at least two scans having different polarization and comprising an L band microwave reflections of the area, wherein the at least two scans are from at least a first sensor for detecting L band microwave radiation reflections, the at least a first sensor attached to an elevated platform located at a remote location above the area;
• filtering electromagnetic noise from one of the at least two scans using at least another scan from the at least two scans to obtain a filtered scan;
• creating a water roughness map based on typical roughness values of a set of types of water sources and the filtered scan;
• identifying at least one type of water sources using the water roughness map and the filtered scan;
• and
• calculating the water content at locations in the area based on the identified at least one type of water sources.
