In this paper, we present an algorithm that interprets the specificities of the received direct path, depending on the particular deformations due to antennas, in the context of Impulse Radio - Ultra Wide Band (IR-UWB) peer-to-peer communications. The goal is to jointly estimate direct path Direction of Arrival (DoA) and Direction of Departure (DoD). The proposed technique is mainly based on prior antenna characterisation and on the prediction of filtering effects due to direct path propagation. Simulation results are provided to illustrate the expected performance of such an algorithm in a simplified scenario. The proposed technique discloses new perspectives for DoA and DoD finding and potentially for wireless context-aware services.
