Abstract"Argon Engineering proposes a synchronized mobile platform Line of Position (LOP) signal intercept and geolocation system using digital narrowband scanning of coordinated wideband receivers. This approach provides precision time and frequency locking ofindependent mobile units under a designated command and control node. To enhance the quality of Electronic Surveillance (ES) during times of Electronic Attack (EA), Argon Engineering proposes to introduce Advanced Event Processing (AEP) and InterferenceCancellation (IC) for robust signal detection and LOP measurement. Time/Frequency Difference of Arrival (TFDOA) geolocation as well as spatial LOP geolocations will be compared for accuracy under various system scenarios. These innovative narrowbandspectrum search and emitter location features will be supported by a LIGHTHOUSE Technology COTS architecture combining Field Programmable Gate Arrays (FPGA) and general purpose digital signal processors using CompactPCI format to reduce size, weight andpower (SWAP). A complete end-to-end simulation will be used to recommend the best system scaling as a starting point for a Phase II demonstration of synchronized mobile units for emitter geolocation. Synchronized spectrum scanning for LOP or TFDOAmeasurements can be accomplished in an efficient hardware environment applicable to a range of platforms including Army PROPHET, Aerial Common Sensor (ACS), Underwater Unmanned Vehicles, and other mo
