| Popis: | In this paper, the localization of a radio frequency emitter (RF) using bearing estimates is investigated. We study the position estimation using a single airborne observer platform moving along a preplanned trajectory. We present results from field trials using an emitter location system (ELS) installed on a vertical take-off and landing (VTOL) unmanned aerial vehicle (UAV). Raw array data batches have been gathered using a six-channel receiver and a fully polarized array antenna. A standard two-step localization approach based on angle of arrival (AOA) measurements and a Direct Position Determination (DPD) approach have been applied. In real-flight experiments, the performance of both methods has been investigated. |
