| Abstract: | Aiming at the multi-baseline interferometer for direction-finding and location of the radar recon- naissance system, the near-field phase consistency calibration introduced wave path difference is analyzed,and a phase error calibration method in the condition of the near-field is proposed. The method is able to eliminate or decrease the effects of the environment factor on the radar reconnaissance system＇s phase error calibration and direction-finding error,and to improve the precision of direction-finding and location. |
