This paper proposes a new computationally efficient direction finding (DF) algorithm that (1) exploits the impinging signals' polarization diversity plus their angular diversity, (2) necessitates only the rooting of two polynomials and no costly iterative searches, (3) estimates elevation angles plus azimuth angles. This paper successfully adopts the Root-MUSIC algorithm to diversely polarized L-shaped arrays. In one two-signal scenario, this new diversely polarized algorithm increases estimation accuracy by almost an order of magnitude and lowers the resolution threshold by 25dB SNR relative to the unpolarized case.
