Abstract
This document presents the Canadian analysis of the data collected during the NATO SCI-222 task group _eld trial held 31 May { 1 June 2012 at Camp Rena military training _eld in Norway. The goal of this joint nations _eld trial was to demon- strate a typical Electronic Warfare (EW) application using Software De_ned Radios (SDRs). The compilation of the results provided by all participating nations will be documented in the _nal SCI-222 Task Group report. The proposed EW application was power-based geolocation of a Radio Frequency (RF) Continuous Wave (CW) transmitter located in the _eld using 8 sensors (SDR receivers) scattered following predetermined test scenarios. The experiment demonstrated that simple and inexpen- sive SDR platforms can be used to perform power-based geolocation with reasonable results accuracy. Improved results could possibly be obtained by either providing re- _ned parameters to the current algorithms or by using more complex algorithms. The experiment also demonstrated that power-based geolocation techniques have limited coverage area around the transmitter. Alternative techniques such as Time Di_erence Of Arrival (TDOA) or Angle Of Arrival (AOA) are probably more suitable for longer range geolocation than power-based, but would require more complex and expensive equipment.
