OneRadio receiver’s unique capabilities – the extreme dynamic range coupled with 2.5 GHz of instantaneous bandwidth, at the affordable low cost – enables persistent (100% duty cycle) monitoring of the spectrum for adversary emissions, even in the presence of strong signals. Three or more minimally networked OneRadio 1.0 receivers can be used to geolocate in real-time adversary emitters, once such adversary emissions are identified. GPS (or exploitable in-theater emissions) can be used to time-synchronize the individual receivers. Key properties of the time-stamped adversary signals can be communicated via minimal network to a common location for TDOA geolocation of the emitter(s).
