Abstract
Fusion of radar and EO-sensors is investigated for the purpose of surveillance in littoral waters is. All sensors are considered to be co-located with respect to the distance, typically 1 to 10 km, of the area under surveillance. The sensor suite is a coherent polarimetric radar in combination with a set of camera's sensitive to visible light, near infrared, mid infrared and far infrared. Although co-located, the sensors are dissimilar and not necessarily synchronized. A critical aspect for beneficial fusion in this application is correct association of information from these sensors. Various architectures are considered and it will be argued that a fuse while track algorithm is the most suitable algorithm in this case. Discussed is how such an algorithm is designed and applied. To improve association reliability also non-kinematic features of both sensor types are considered. Investigated in particular is, which features from contacts measured with the polarimetric radar and the EO-sensors are correlated. These features and their correlations are incorporated in the tracking process. Preliminary results are shown.
