根据干涉仪测向的基本原理，分析了干涉仪测向误差产生原因，提出了近场试验条件下的相位误差校正方法，可消除试验条件对测向误差的影响，提高试验结果可信度。仿真结果说明，本文提出的内场干涉仪测向误差校正方法可显著减少内场测试的影响。%Based on the basic principle of the direction finding of the interferometer, the causes resulting in the direction-finding error are analyzed, and a phase error calibration method in the condition of the near-field test is proposed to eliminate the effects of the test condition on the directionfinding error and to improve the reliability of the test results. The simulation results indicate that the calibration method of the direction-finding error presented can greatly reduce the effects of the inter- nal-field test.
