Abstract :
A recent method proposed by J. Liang and D. Liu in “Joint elevation and Azimuth direction finding using L-shaped array,” IEEE Trans. Antennas Propag. vol. 58, no. 6, pp. 2136-2141, Jun., 2010, has a constraint that it cannot resolve the sources which share the same joint electric angle: θ = Φ - γ. This comment proposes a solution to this constraint and validates the concept through a simulation example.
