摘要：
In this paper, a novel photonics-assisted joint frequency and direction of arrival (DOA) estimation system is proposed. The system is based on the uniform linear array (ULA). Each channel connects to an array element and contains two Mach-Zehnder Modulators (MZM). The same PRBS is mixed with all channels in the optical domain. As a result, the frequencies and DOAs of the signals can be successfully estimated simultaneously without explicit pairing.
