Passive Localisation Using a Blind Interferometer on a Single UAV

This paper considers the problem of passive location using an interferometer on a single UAV. In conventional algorithm both measurements of baseline vector and initial phase difference are necessary to locate the target, which reduces the reliability of location system for the fact that the measurements may be polluted by noise or almost unavailable in practice. Therefore, a novel target location method without using the measurements of baseline vector and initial phase difference is proposed in this paper. Simulation results show that the proposed algorithm performs better than conventional algorithm when the measurements noise is relatively large. (paper)
