摘要
相位干涉仪测角是反辐射雷达导引头较常采用的一种测向体制,通常采用长、短基线的方式解决测角模糊问题。论述一种旋转式干涉仪测角系统能够利用弹体自身旋转解决测角模糊问题,通过数字仿真说明了该系统的正确性。该系统中可变延迟线的特性直接影响测角性能,提出的数字化方案能够较好地解决该问题。
The method of angle measure based on phase interferometer is widely used in passive radar seeker（PRS）,and the main problem is the angle-measure ambiguity.A method based on rotated phase interferometer can solve the problem.Microwave phase delay line in the system is the key factor to interfere the accuracy of the system,and a digital method discussed in the paper can solve the problem.
