Abstract

In the direction-of-arrival estimation, the diffraction of the incident signal from antenna platforms is often neglected or considered as a source of clutter. Motivated by human auditory system which exploits the diffraction of the sound from the head, we show that the multipath produced by the antenna platform can be utilized to improve the accuracy of estimation. We conduct the analysis on a realistic model of airborne platform. We use the Cramer-Rao bound to assess the level of improvement due to the presence of the platform.
