| Abstract: | The influence of multipath effect on phase difference between antenna array elements is analyzed on the basis of the computation model of phase relation under three multipath conditions, that is scattering body surrounding the emitting plat with the direct path, without the direct path, and strong reflecting paths with a great distance. The computer simulation and the theoretical analysis on statistical character of phase relation are carried out. The model is suitable for simulating vector channel parameters in multipath case, which provides a reference for researching a new Direction Finding algorithm for Director of Arrival(DOA) by the use of phase parameters. |
