[Technical Report] Multi-frequency calibration for DOA estimation with distributed sensors

Abstract : In this work, we investigate direction nding in the presence of sensor gain uncertainties and directional perturbations for sensor array processing in a multi-frequency scenario. Specically, we adopt a distributed optimization scheme in which coherence models are incorporated and local agents exchange information only between connected nodes in the network, i.e., without a fusion center. Numerical simulations highlight the advantages of the proposed parallel iterative technique in terms of statistical and computational eciency.
