The problem may also occur in liquid or elastic designs to some extent, but you have much more design freedom there.
这个问题在一定程度上也可能出现在流设计或弹性设计中，但是那种设计有更大的设计自由度。
Generally if a target is to be simulated by a 3-element antenna array in the limited space of a laboratory, inhomogeneity to some extent of the amplitude and the phase will occur.
要在实验室有限空间内用三元天线阵列模拟目标，就得承受一定的幅度和相位不均匀性。
