| 摘 要： | 在射频仿真系统中，精确的目标位置通过“三元组”幅相控制实现，幅相控制误差直接影响阵列上目标位置的模拟精度。详细推导了角闪烁方程，以此建立了幅控误差传播模型，提出了相控误差传播的等效分析方法，分析了幅相控误差对目标位置精度影响的基本规律。基本分析结论经仿真验证正确，具有工程指导意义。

| Abstract: | Accurate target position of RFSS is simulated by control of the amplitude and phase of a three-element-array and the amplitude and phase control errors directly affect the target position. Based on detailed derivation of angular scintillation equations, this paper establishes an amplitude control error propagation model and proposes equivalent analysis method for phase control error propagation, It also analyzes the basic regularity of influence of amplitude and phase control errors on accuracy of target positions. The conclusions are verified through simulation and are of high significance to engineering applications. |
