Direction of arrival (DOA) estimation of radio waves is applicable to localization of users in mobile communication and radar systems. In addition to MUSIC and ESPRIT, which are well-known traditional algorithms, compressed sensing has been used for DOA estimation with the development of computing resources. Although compressed sensing requires larger computational load, it has a higher accuracy compared with MUSIC in general. If such a large computational load is acceptable, it is expected that we can obtain higher estimation accuracy by applying deep learning. In this paper, we design a network suitable to the case where two narrow-band signals with close DOAs impinge on a linear array and examine its characteristics. In addition, we consider the case where two networks trained with and without close DOAs restriction are used in parallel. Simulations show that higher estimation accuracy than MUSIC is obtained in the close DOAs situation and that the performance highly depends on the training models. |
