dc.description.abstractThis dissertation presents a study of techniques for accurate indoor/outdoor electromagnetic radiation (EMR)/electromagnetic compatibility (EMC) measurement in the presence of interferences. The basic idea is to use an antenna array plus array signal processing instead of a single antenna as the receiving antenna in an EMR or EMC measurement. The methodology is to combine array antennas, array data acquisition, direction of arrival (DOA) estimation, and adaptive beamforming techniques to detect and suppress interferences. Through theoretical stud y, numerical simulation, and hardware experiments, it clearly proves that interferences ca n be effectively suppressed and the studied topic is valid and useful in applications. For the array antennas, we considered a uniform linear of 8 elements; we studied many DOA estimation algorithms, but we mainly adopt the popular and powerful MUSIC algorithm in the numerical simulation study and in processing experimental data. For interference suppress ion, only one strong interference is considered for adaptive beamforming. This study only presents preliminary and basic exploration of the studied topi c and shows its validity and use fulness. For serious measurement applications, much more works needed to be done with careful design of measurement set-up, more sophisticated signal processing algorithms and customized hardware to achieve better performance.en_US
