On the broadband effect of remote stations in DPD algorithm

Abstract

This paper addresses the direct geolocation of sources in one step via a multi-base (or multi-array) context. The 1-step methods such as DPD and LOST are working on a global array composed of all the sensors of each base. However, even if these algorithms introduce a narrowband decomposition (unfortunately imperfect), these recent powerful algorithms can be disturbed by the residual broadband effect due to the partial coherence of signals (even incoherent signals) between stations. The main contribution of this work is to study the DPD performance in presence of a residual array-broadband effect.
