System and method for large-scale radio frequency signal collection and processing
A large-scale radio frequency signal collection and processing system comprising a plurality of sensor systems mounted on a plurality of collection platforms that integrates a plurality of overlapping datasets with differing characteristics (e.g., different resolutions, different view angles, different heights, different time periods, unrelated types of data) to generate an enriched dataset or datasets using a variety of processing techniques (e.g., statistical analysis, signal processing, image processing) that allows for more comprehensive analysis of the radio frequency signal landscape than would be possible using any of the datasets individually, or in combination but without such integration.
1. A system for large-area, wide-bandwidth radio frequency signal collection and processing, comprising:
one or more collection platforms, each comprising: one or more radio frequency sensor systems configured to capture signal information comprising radio frequency data; and one or more metadata collectors configured to capture signal information comprising metadata about the radio frequency data, including at least a time, a frequency, and a location of capture; and
an emission source analyzer comprising a processor, a memory, and a plurality of programming instructions stored in the memory which, when operating on the processor, cause the processor to: receive signal information from one or more of the collection platforms; identify one or more radio frequency signals from an emission source; determine a scope of data collection for generation of radio frequency landscape information for the emission source; and based on the determined scope of data collection, direct one or more of the one or more collection platforms to collect more detailed data, less detailed data, wider area data, narrower area data, higher resolution data, and/or lower resolution data either by the same sensor at a different location or time, or by at least one other sensor system on a related or unrelated collection platform or platforms;
an enriched dataset generator comprising at least a plurality of programming instructions stored in a memory which, when operating on a processor, cause the processor to: receive a plurality of datasets comprising pre-processed signal information and further comprising at least one common or overlapping characteristic; separate each dataset into at least a spatial component, a time domain component, and a frequency domain component; map each element of each component of each dataset to their analogues in each of the other datasets in the plurality of datasets; develop statistics and metrics for one or more of the components; and combine the plurality of datasets, their components, and the mapping between them into a single dataset of higher information content than any one of the datasets comprising the plurality of datasets.
2. The system of claim 1 , wherein the enriched dataset comprises sufficient information to produce a geographical map of radio frequency signals in a given area.
3. The system of claim 1 , wherein the enriched dataset further comprises derivative information allowing production of a geographical map of radio frequency signals in a given area supplemented with analysis and statistics of radio frequency activity.

7. A method for large-area, wide-bandwidth radio frequency signal collection and processing, comprising the steps of:
capturing signal information comprising radio frequency data and using radio frequency sensor systems on one or more collection platforms;
capturing signal information comprising metadata about the radio frequency data, including at least a time, a frequency, and a location of capture, using metadata collectors on one or more collection platforms; and
receiving signal information at an emission source analyzer from one or more of the collection platforms;
identifying one or more radio frequency signals from an emission source;
determining a scope of data collection for generation of radio frequency landscape information for the emission source; and
based on the determined scope of data collection, directing one or more of the one or more collection platforms to collect more detailed data, less detailed data, wider area data, narrower area data, higher resolution data, and/or lower resolution data either by the same sensor at a different location or time, or by at least one other sensor system on a related or unrelated collection platform or platforms;
receiving into an enriched dataset a plurality of datasets comprising pre-processed signal information and further comprising at least one common or overlapping characteristic;
separating each dataset into at least a spatial component, a time domain component, and a frequency domain component;
mapping each element of each component of each dataset to their analogues in each of the other datasets in the plurality of datasets;
developing statistics and metrics for one or more of the components; and
combining the plurality of datasets, their components, and the mapping between them into a single dataset of higher information content than any one of the datasets comprising the plurality of datasets.
