Method for Mapping and Analysis of Electromagnetic Background in Urban Area

This paper presents a method for mapping and analysis of electromagnetic background in an urban area. The uniqueness of our environment causes the inability to simulate electromagnetic fields of the real world as there is an unknown amount of sources and a near infinite amount of obstacles that could obscure the traveling wave or bounce it in a different direction altogether. The proposed method allows mapping an area of 64 hectares in less than 24 hours using only one person, antenna, software-defined radio, laptop, and optionally external drive to store data, which ensures the possibility of having multiple setups to multiply results. The general analysis of gathered data consists of three parts. The first is the compression ratio, a valuable byproduct of data compression for long-term storage. The second uses geographical locations to determine variance by distance, in a straight line and a cluster. The final tool for analysis is a Pearson’s and Kendall’s correlations to a baseline measurement to find potential errors and/or anomalies within a data set.
