A Direct Position Determination Method under Unknown Multi-Perturbation with Moving Distributed Arrays

Distributed array manifold perturbation, which includes synchronization errors, amplitude-phase and path attenuation, has seriously degraded the accuracy of existing direct position determination (DPD) methods. In this paper, a DPD method under unknown multi-perturbation with moving distributed coprime arrays is advocated for. Firstly, by means interchange, integrated signals received from can be fused, contributes to multi-position fusion. Subsequently, resorting orthogonality between noise subspace steering vector via arrays, quadratic optimization problem constructed. Finally, we realize multi-parameter decoupling achieve localization regardless perturbations. The superiority substantiated simulation examples.
