Orthogonal Least Squares with Integrated Information Theoretic Criteria for Joint Number of Targets and DoA Estimation

Fran\c{c}ois Horlin, Gilles Monnoyer, J\'er\^ome Louveaux, Martin Willame

Integrating information theoretic criteria into orthogonal least squares enables joint estimation of the number of targets and their directions of arrival.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Numerical simulations show that the proposed hybrid ITC-OLS algorithm consistently outperforms both the other proposed variants and a baseline method from the literature.

C2weakest assumption

That embedding the ITC penalty inside the OLS greedy steps preserves the statistical consistency of model-order selection without introducing bias from the sequential nature of the search.

C3one line summary

Hybrid ITC-OLS algorithm integrates model-order selection into greedy DoA estimation and outperforms other variants and a literature baseline in simulations.
