有源阵单元相位误差对波束指向的影响

The Effect of the Phase Deviation of Array Elements on Beam Direction in Active Antenna Array

从实用观点出发，研究了高频天线阵单元相位误差对波束的影响．在进行了数学推导后，还讨论了实际应用中减小这种影响的具体办法．按这种方法实现了对有源天线单元的布置．

From the practical application view-point,the effect of the phase deviation of array elements on beam direction is analysed. After the expression is deduced,some methods used to reduce the effect are given.
