System and method of underground water detection

A system for determining underground polar liquid 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, from a radiofrequency radiation sensor, a main scan of an area, the main scan including reflections at a radiofrequency range, from locations in the area the sensor being attached to an object located at least 50 meters above the area;
• receive typical roughness values of various types of polar liquid sources;
• filter from the main scan one or more undesired polar liquid source types according to their typical roughness values;
• identify a desired type of polar liquid source in the filtered main scan;
• receive from the radiofrequency radiation sensor a set of scans of the area, each scan comprising reflections at the radiofrequency range taken from the locations in the area prior to the receiving of the main scan;
• and
• calculate the underground polar liquid content at the locations in the area based on the identified desired type of polar liquid sources and the received set of scans.
