The realization of radar reconnaissance system's phase calibr ation method of near-field

对采用多基线相位干涉仪进行测向定位的雷达侦察系统,分析在近场条件下进行相位一致性校正时引入的波程差,提出了近场条件下的相位校正方法。该方法可有效地消除或减小环境因素对雷达侦察系统相位校正和测向误差的影响,从而提高测向和定位精度。

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.
