For locating maritime vessels longer than 45 meters such vessels are required to set up an Automatic Identification System AIS used by vessel traffic services. However when a boat is shutting down its AIS there are no means to detect it in open sea. In this paper we use Electro-Optical EO imagers for noncooperative vessel detection when the AIS is not operational. As compared to radar sensors EO sensors have lower cost lower payload and better computational processing load. EO sensors are mounted on LEO microsatellites. We propose a real-time statistical methodology to estimate sensor Receiver Operating Characteristic ROC curves. It does not require the computation of the entire image received at the sensor. Wethen illustrate the use of this methodology to design a simple simulator that can help sensor manufacturers in optimizing the design of EO sensors for maritime applications. 1. Introduction Since a couple of years the number of illegal acts for taking control of maritime vessels has increased. For search-and-rescue reasons it is suitable to find efficient sensor systems for detecting vessels. Vessel candidates for
