Research on AOA estimation methods for arbitrary structured arrays

Dianxin kexue
Direction of arrival (DOA) estimation is a critical area in array signal processing, with angle of arrival (AOA) being its core parameter. AOA estimation was taken as the main research objective to enhance accuracy in arbitrary structured arrays.
