干涉仪测向具有精度高、速度快的特点，在无源探测定位系统中具有广泛的应用。传统干涉仪依靠短基线保证无模糊测向范围，依靠长基线保证测向精度，采用整数阶基线比。该方法在宽带应用条件下难以实现，且对天线阵的安装位置非常敏感。本课题研究分数阶干涉仪测向的算法，同时实现宽带、高精度、无模糊的要求，并研究不同分数比、相位测量误差对测向精度的影响，进行仿真验证。 (interferometer is measured to high accuracy and fast, in the passive position detection system has wide application. Rely on traditional interferometer no guarantee short baseline measurement to the scope of fuzzy, relying on long baseline measurement to ensure accuracy, using integer band than the baseline. The method in broadband applications under difficult conditions and the right antenna installation location is very sensitive. The research fractional interferometer to test the algorithm, while achieving wide-band, high-precision, without ambiguity, and different than the scores, phase measurement error to the measurement accuracy of the impact simulation test.)
