互质数

对双基线系统余数定理解模糊原理作了分析，提出了虚拟阵元概念，清晰地解释了基线长度之比为互质数之比的多基线系统的相位解模糊能力。

The principle for resolving ambiguity in dual baseline system is analyzed by using theorem of remainder and the concept of imaginary array is presented .

根据虚拟阵元概念，解释了基线长度之比为互质数之比时多基线系统的相位解模糊算式，并提出了基于免疫算法的解模糊方法。

According to the fictitious first concept of battle array have explained the length of base line Zhi than is mutual prime number Zhi than the phase of the much system of base line untie vague calculate type , and have put forward based on immunity algorithm untie vague method .
