| 摘 要： | 比幅比相测角是宽带被动雷达测向系统中的一种重要方法，由于比幅比相测角系统存在相位多值模糊，因此采用长短基线和幅度信息，提出了划分幅度差门限设置滑动粗相位的方法．并通过实验证实了其有效性，实现了比幅比相测角的解多值模糊，在实际工程应用上具有一定的实用价值和参考价值．

| Abstract: | Measuring angle by comparing amplitude and phase is an important method in wide-band passive radar seeker technology. Because of existence of several values in phase. The system of measuring angle by comparing amplitude and phase will yield fuzziness. The long-short baselines and information of amplitude are employed to establish a method of setting stiding coarse phase according to the threshold of amplitude difference. Its validity is proved by experiment. The fuzziness is eliminated in the system of measuring angle by comparing amplitude and phase. It has certain reference and application values in actual projects. |
