Abstract
The Reserach Study Group 5 of NATO AC/243 Panel 4 organized a measurement campaign to improve knowledge of environmental factors that impact on IR Search and Track system performance in the marine boundary layer. The campaign, called LAPTEX (Low-Altitude Point-Target Experiment), was conducted in July 1996 at NATO FORACS near Souda, on the island of Crete (Greece). At LAPTEX, Canada focused on sessions of tracking of near sea-surface point-targets. During these sessions, Canada performed high resolution imaging in the visible to assess refraction and turbulence effects, while the other participating nations made observations in the two IR bands using different system configurations. Spectral radiometry of the background at the air-sea interface was performed and the atmospheric extinction along with the air turbulence structure parameter (Cn2) were measured at sea. Finally, as meteorological support to the campaign, Canada performed radiosonde measurements at sea and deployed a wave-buoy that provided detailed information on the sea surface structure. The data collected at LAPTEX will be used to validate models that are currently being developed, which are aimed at analyzing system performance and optimizing signal processing algorithms.
