Systems, methods, and devices enable spectrum management by identifying, classifying, and cataloging signals of interest based on radio frequency measurements. In an embodiment, signals and the parameters of the signals may be identified and indications of available frequencies may be presented to a user. In another embodiment, the protocols of signals may also be identified. In a further embodiment, the modulation of signals, data types carried by the signals, and estimated signal origins may be identified. |

1. A spectrum analysis and management device, comprising:
a device within a housing including a radio frequency (RF) receiver coupled with at least one processor, 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, both corresponding to at least one signal of interest;automatically determine a geographic location of the at least one signal of interest based on the received location input data;automatically determine a time associated with the RF energy measurements and convert the received RF energy measurements into spectral representation data;automatically process spectrum power density data as received and process in-phase quadrature (I/Q) data by fast parallel adaptive filter processes to generate a power spectrum;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;automatically identify the signal(s) of interest in near real-time for the received location input data and RF energy measurements based upon whether the signal parameter(s) of the signal(s) of interest matches any signal parameters in the signal characteristic listing data;automatically determining a modulation type, a protocol, and a symbol rate for each of the identified signal(s) of interest; wherein the signal parameter data, the modulation type, the protocol, the symbol rate, the location of the device, and the time associated with the RF energy measurements are automatically stored in a history database in the memory; and wherein the display is operable to provide a visual representation of the signal(s) of interest and the corresponding identification including the signal parameter data, the modulation type, the protocol, the symbol rate, the location of the device, and the time. |
