Systems and methods for analyzing signals of interest

A spectrum analysis system comprising:

• a radio frequency (RF) receiver;
• a device including a processor and a memory;
• a display;
• and
• a location receiver;
• wherein the at least one processor is operable to:
• receive location input data from the location receiver and RF energy measurements from the RF receiver for at least one signal of interest;
• determine a geographic location of the at least one signal of interest based on the received location input data;
• determine a time associated with the RF energy measurements and convert the received RF energy measurements into spectral representation data;
• analyze the spectral representation data to identify the at least one signal of interest above a power threshold and determine at least one signal parameter of the signal of interest;
• compare the at least one signal parameter of the at least one signal of interest to signal characteristic listing data in the memory to determine whether the at least one signal parameter of the at least one signal of interest matches corresponding signal parameters in the signal characteristic listing data;
• identify the at least one signal of interest in near real-time for the received location input data and RF energy measurements based upon whether the at least one signal parameter of the at least one signal of interest matches any signal parameters in the signal characteristic listing data;
• wherein the device is operable to determine whether sample data associated with the at least one signal of interest is valid signal data or noise;
• wherein the device is operable to discard the sample data when the sample data is noise;
• wherein data relating to the at least one signal parameter of the at least one signal of interest, the geographic location of the at least one signal of interest, and the time associated with the RF energy measurements are stored in the memory;
• and
• wherein the display is operable to provide a visual representation of the at least one signal of interest including the geographic location of the at least one signal of interest.
