Direction of arrival (DOA) estimation is an important topic for a wireless communication area. So far, the multiple signal classification (MUSIC) algorithm is the most popular one in the field of DOA estimation because it is noticeably simple but effective. However, the resolution becomes low when the number of snapshots is not appropriate for the received signal power. Therefore, this paper proposesan adaptive snapshot technique to solve the aforementioned problem. The idea is to have a DOA finder which is able to adapt the snapshot numbers according to the received power to maintain the accuracy of the DOA estimation. A DOA finder prototype is also constructed to validate the proposed idea.
