Cramér-Rao Bound on Lie Groups with Observations on Lie Groups: Application to SE(2)

Samy Labsir, Alexandre Renaux, Jordi Vilà-Valls, Éric Chaumette

ICASSP 2023accepted

In this communication, we derive a new intrinsic Cramér-Rao bound for both parameters and observations lying on Lie groups. The expression is obtained by using the intrinsic properties of Lie groups. An exact expression is obtained for the case where parameters and observations are in SE(2), the sem…

Tracking a Cluster of Space Debris in Low Orbit by Filtering on Lie Groups

Samy Labsir, Audrey Giremus, Guillaume Bourmaud, Brice Yver, Thomas Benoudiba-Campanini

ICASSP 2019accepted

This paper addresses the problem of tracking a cluster of space debris sufficiently close to each other to be considered as a single ex-tended object. State-of-the-art random-matrix methods estimate the kinematics of the object centroid by assuming that its shape is elliptic and that the observation…
