| Abstract: | For the problem of phase difference ambiguity using multi-baseline interferometers in direction finding, a new method is proposed for solving the phase difference variety ambiguity by stagger distance difference after the analysis of the phase difference. The conditions, range and the relationship between the angle of incidence and the estimation accuracy of direction of arrival are discussed. At last, the simulation results are given. |
