The work proposed will develop and implement commercially viable gradient detection methods and
algorithms for localizing radiation sources using a single non‐directional detector. Exploitation of
gradients introduced by source‐to‐detector distance – through natural or deliberate motion – and those
introduced by body‐shielding will allow for enhanced localization and tracking of sources in a
pedestrian‐based search scenario. Appropriate available technologies for position determination (COTS
MEMs‐based IMUs) will be selected and integrated into pre‐production spectroscopic radiation
detection platforms. Algorithms to extract relative positioning from IMU data will be developed and
implemented, and existing advanced Bayesian inference algorithms will be updated to utilize relative
position data. The goal of the Phase II program is to provide fully integrated and tested pre‐production
radiation detectors with the improved search capability for further evaluation and CONOPs
development. These pre‐production devices will demonstrate the commercial viability of the enhanced
search algorithms within a networked system of commercial radiation detectors.
