I have an FMCW automotive radar simulation and trying to estimate azimuthal direction of reflected wave from one target. Using a ULA, trying to setup the algorithm but I just don't know which function is best to use. Thank you for any advice.

They do the same thing, the difference is on interfaces. rootmusicdoa takes the covariance matrix as input while phased.RootMUSICEstimator take the row data as input. The RootMUSICEstimator can also help you estimating the number of sources in the signal. But you can use either one of them to achieve your goal depending on what kind of data you have.
