Resumo
This letter proposes a novel robust mitigation technique
to address the problem of target localization in adverse nonline-
of-sight (NLOS) environments. The proposed scheme is based
on combined received signal strength and time of arrival measurements.
Influence of NLOS biases is mitigated by treating them as
nuisance parameters through a robust approach. Due to a high
degree of difficulty of the considered problem, it is converted into a
generalized trust region sub-problem by applying certain approximations,
and solved efficiently by merely a bisection procedure.
Numerical results corroborate the effectiveness of the proposed
approach, rendering it the most accurate one in all considered
scenarios.
