一种基于双波段的相位差解模糊处理方法

针对比相测角过程中的相位差模糊问题,给出了一种基于双波段(如L/C)的联合解模糊的处理方法,分析了得到正确实际相位差值的条件和范围.该方法采用双波束比相法测角,利用2个波段工作条件下的模糊数估计值之间的内在联系,通过一维搜索实现了相位差模糊的解算.仿真结果验证了该方法的可行性.

A Method of Processing Phase Difference De-ambiguity Based on Dual-band

For the problem of phase difference ambiguity in measuring angles using the phase comparison, a method was proposed for processing the joint de-ambiguity in terms of the dual-band (L/C), and the condition and range of acquiring the really correct phase difference was analyzed. The proposed method adopts two beams phase comparison to measure the angle, and implements the de-ambiguity of phase difference using the internal relation of ambiguous value estimation under the circumstance of operation in the dual band by means of one dimension search. By simulation it shows that the proposed method is feasible.
