基于DBF的相位干涉仪解模糊原理与实现

由于受到天线间互耦的影响，传统的利用短基线来解相位干涉仪模糊的方法受到了一定的限制．数字波束形成技术由于数字处理的灵活性，可获得超出普通天线的性能，也为解模糊问题提供了一个新思路．在详细介绍数字波束形成的基本原理的基础上，对DBF技术用于解相位模糊的可行性进行了分析与论证．最后结合实际工程项目给出了具体的实现方法．

Principle and implementation of phase ambiguity resolution of interferometer based on DBF

The traditional method which uses the short baseline to overcome phase ambiguity of the phase interferometer is restricted because of the mutual coupling between antennas.Greater capabilities than the common antenna can be achieved by using the technology of digital beam forming(DBF) because of flexibility in digital signal processing,providing a new approach to the problem of phase ambiguity.The feasibility of using DBF to resolve phase ambiguity is analyzed and demonstrated based on the basic principle of DBF.The concrete method to implement the idea is given in combination with a practical project.
