Patent ID: 8446310

Claim:
A method comprising: receiving signal data generated at one or more monitor systems operable to monitor for electromagnetic signals, the signal data related to a plurality of characteristics of a first signal, the plurality of characteristics of the first signal comprising at least two of: a respective power of the first signal as measured at each of the one or more monitor systems; a respective frequency of the first signal as measured at each of the one or more monitor systems; a time the first signal arrived with respect to each of the one or more monitor systems; and an angle the first signal arrived with respect to each of the one or more monitor systems; accessing, by a computing system, situational data, wherein the situational data includes information of a physical condition at a location proximate to the one or more monitor systems, wherein the physical condition at the location proximate to the one or more monitor systems is selected from the group consisting of: the respective locations of at least two of the one or more monitor systems relative to each other; a physical terrain topography; a manmade topography; a value indicating the population density located within a predetermined range of the one or more monitor systems; and the weather at the one or more monitor systems; selectively discarding, automatically by the computing system, received signal data according to a signal characteristic, the discarding based at least partially on the information of the physical condition; calculating by the computing system a location of a source of the first signal at least in part by processing retained signal data according to a signal characteristic to generate a preliminary location for the signal characteristic and blending preliminary locations generated for the plurality of characteristics of the first signal; and determining that the first signal is jamming a second signal, the determination based at least in part on the calculated location.
