分析了用于头盔瞄准具的电磁敏感系统的系统误差,提出了一种校正方法。该方法可一次校正由于工作环境不良引起的电磁场畸变以及由于三轴天线轴不正交所产生的系统误差,其可行性已被计算机模拟和实验所证明。
The systematic errors of the electromagnetic sensitive system used in the helmet sight are analyzed and a correction method is proposed. The method can correct the electromagnetic field distortion caused by the poor working environment and the systematic error caused by the non-orthogonal triaxial antenna axes. The feasibility has been proved by computer simulation and experiment.
