A comparison of two source azimuth estimation schemes
Neeraj Magotra, Nasir Udin Ahmed, Eric P. Chael · IEEE Transactions on Acoustics Speech and Signal Processing · 1987
This correspondence compares two azimuth estimation schemes via a simulation, based on the estimated values and the corresponding variances. The comparison is an empirical one, and no claims are made about either scheme reaching the Cramer-Rao lower bound. Both of the schemes operate on single station data as opposed to standard techniques developed for array data.
