Due to the complexity and amplitude-phase inconsistencies in traditional multi-channel interferometer and array
two phase difference observation models for direction finding based on the rotated long baseline interferometer(RLBI)is analyzed.The unambiguous direction finding conditions for the proposed models are derived.A multiple hypothesis pseudolinear iteration least square(MHPILS)algorithm is proposed.The Cramer-Rao low bound(CRLB)and mean square error(MSE)is also analyzed.The simulation results show that this method achieves moderate computation amount and can attain the CRLB.
