舰载数字相控阵雷达在交付列装前需开展坞内的静态标校和出海航试的动态标校，其数据分析是一项重要的工作。本文介绍标校工程实施方案，建立基于雷达测量目标方向向量的电子平台坐标转换模型，分析阵面姿态和舰姿态数据对雷达测角精度的影响；不同扫描角下的姿态参数误差传递不同，与雷达测角指标要求相结合，对雷达标校误差样本的异常数据进行分析。仿真和实际试验应用表明，该方法有助于标校数据分析和平台参数装订误差收敛，对雷达生产工程试验有指导性意义。
The shipborne digital phased array radar needs to carry out static calibration in dock and dynamic calibration in sea trial before delivery and installation, and the data evaluation is an important work. It introduces the implementation scheme of calibration project, establishes the electronic platform correction model based on direction vector for radar measurement target, analyzes the influence of array attitude and ship attitude data on radar angle measurement; analyzes the abnormal data of the calibration error samples according to the combination with requirements of radar angles measurement index and differences of the error transmission of attitude parameters under different scanning angles. Simulation and practical test application show that the method is helpful for analysis of calibration data and convergence of platform parameter binding error, and has a guiding significance for radar production engineer.
