    • Detection metrics and ship [D]RI 

      Van Rheenen, Arthur D.; Heen, Lars Trygve; Madsen, Eirik Blix; Brendhagen, Erik; Løkken, Kristin Hammarstrøm; Almklov, Bernt; Glimsdal, Eirik (2018)
      Well-known detection metrics based on Johnson criteria or Target Task Performance (TTP) models were developed for land-based targets [1,2]. In this paper we investigate how (whether) we can apply these metrics to especially ...

    • Measurements of IR propagation in the marine boundary layer during the September 2011 SQUIRREL trial 

      Heen, Lars Trygve; Rheenen, Arthur Dirk Van; Brendhagen, Erik (2012)
      A multinational field trial (SQUIRREL) was performed at the Eckernförder Bucht, in the Baltic Sea, during September 2011 to study infrared ship signature and atmospheric propagation effects close to the sea surface in a ...

    • Obtaining spectral information from infrared scenarios using hyper-spectral cameras and cameras with spinning filter wheel 

      Glimsdal, Eirik; Brendhagen, Erik; Thomassen, Jan Brede; Rheenen, Arthur Dirk Van; Heen, Lars Trygve (2014)
      In the past decades the Norwegian Defence Research Establishment (FFI) has recorded and characterized infrared scenarios for several application purposes, such as infrared target and background modeling and simulation, ...
