摘要：
Ocean surface current radar has attracted attention as a system which can be observed ocean phenomenon effectively. In this report, we evaluate the aperture enhancement effect by applying the Khatri-Rao (KR) product array to the Doppler frequency and angular resolution. Since Doppler frequency represents surface current velocity, resolution enhancement leads to estimation accuracy improvement of the velocity. In this paper, we apply the KR product to actual data set of the ocean surface current radar, and estimated surface current velocity.
