Optical characteristics of small surface targets, measured in the False Bay, South Africa; June 2007

During the False Bay trial (June 2007), the performance of a set of three optical sensors was tested against several small surface targets in a coastal area: a hyperspectral camera, a camera with a rotating polarization filter and a high resolution camera. One objective was the validation of a contrast and clutter model for the visual spectral...

Small maritime target detection through false color fusion

We present an algorithm that produces a fused false color representation of a combined multiband IR and visual imaging system for maritime applications. Multispectral IR imaging techniques are increasingly deployed in maritime operations, to detect floating mines or to find small dinghies and swimmers during search and rescue operations. However...

IRST and its Perspective

This paper starts with a review of the status of presently available IRST sensors and continues with the problems that they are facing, even after more than 25 years of development. The problems arise from uncertainty in target signatures, atmospheric effects, background clutter and different types of hardware and processing shortcomings. Yet...
