- Abstract
- A study on the infrared signature of a naval ship by the solar elevation has been performed using well known IR signature analysis software, ShipIR/NTCS. The contrast radiant intensity of a ship against the Eastern Sea background from sunrise to noon has been investigated. Monthly averaged climate data for both January and July have been applied to investigate seasonal change of the signature. A study on the signature for different ship speeds has been carried out as well. Simulation results show that the maximum signature in both wave-bands for a sea-level observer happens around the 25～35 degree of solar elevation and it is highly dependent on the ship geometry rather than solar irradiance.
