    • 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 ...

      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, ...

    • SIMVEX 2001 trial - radiant intensity contrast 

      Stark, Espen; Heen, Lars Trygve; Wikan, Kjell (2002)
      FFI project 801 “IR-missiles” participated in the SIMVEX (Ship Infrared Model Validation EXperiment) trial organized by NATO RTO/SET/TG16 “Infrared measurements and modeling for ship self defense” in September 2001 in ...

    • SIMVEX 2001 trial - spectral IR measurements 

      Heen, Lars Trygve; Brendhagen, Erik (2002)
      The ship signature model ShipIR/NTCS has been selected as a NATO standard. In 2001 several nations, including Norway, participated in the SIMVEX field trial arranged by NATO in Canada for validation of this model. ...
