摘　　要：高精度相控阵天线指向的关键在于保证各通道幅相特性的一致性。文中针对一种小型圆口径相控阵天线对影响指向误差的主要因素进行了阐述和仿真分析,提出了降低误差提高指向精度的方法。该文对小口径条件下的相控阵天线研制有一定的工程指导意义。For phased array antennas, the key to high beam-steering accuracy is the uniformity of channels amplitudes and phases. Based on the small & circular shape antenna, firstly, the chief factors are analysed. Then, the methods of reducing errors are introduced. This work has certain instructional significance to relevant engineering practice of small phased array antennas.
