Paper Abstract

In order to detect an object, the object has to be distinguished from its background. Often a contrast number is defined, the difference between the signals from the object and its background. Hence, detailed knowledge of both is required. Background measurements made during two measurement campaigns are compared with results from ShipIR modeling efforts. Specifically, background radiance profiles, extracted from infrared camera recordings and spectrometer recordings of the sea and sky, and spectral features are highlighted.
