摘　　要：阐明了近场效应产生的原理,推导了二元定向公式,并对其进行了建模仿真,得出其对系统精度的影响程度。建立了阵面及转台回转中心关系的模型,利用模型推导了幅度误差和相位误差对目标位置精度的影响,然后对衰减器与移相器幅相漂移产生的原因进行了分析,并提出了各种误差的补偿办法。最后给出了系统误差产生的顺序。The principle ofnear-field effect is described and the equation that determines the direction of a twosome of antennas is derived. The effect of system accuracy with modeling method by amplitude and phase error is pointed out. And then the reasons is analysed with a new point of view that the attenuator and phase inverter drifts are produced. Compensated means for each kind of error are proposed. At the last, the order of the system error is given.
