The Geometry of Generalized Likelihood Ratio Test [PDF]
Entropy, 2022 The generalized likelihood ratio test (GLRT) for composite hypothesis testing problems is studied from a geometric perspective. An information-geometrical interpretation of the GLRT is proposed based on the geometry of curved exponential families.

Distributed Target Detection in Unknown Interference [PDF]
Sensors, 2022 Interference can degrade the detection performance of a radar system. To overcome the difficulty of target detection in unknown interference, in this paper we model the interference belonging to a subspace orthogonal to the signal subspace.
