In polar region operations, drift sea ice positioning and tracking is useful for both scientific and safety reasons. Modeling ice movements has proven difficult, not least due to the lack of information of currents and winds of high enough resolution. Thus, observations of drift ice is essential to an up-to-date ice-tracking estimate. As an inverse problem, it is possible to extract current and wind...
Multiple complementary sensors can be valuable when designing a robust target tracking system for collision avoidance on a moving platform. In this paper, the achievable performance of several sensor configurations are assessed using the Cramer-Rao Lower Bound (CRLB) and an alternative performance measure closely related to the Extended Kalman Filter (EKF). Targets are modeled using constant velocity...
