摘　　要：为了提升嵌入式综合光电瞄准系统的测量精度,对系统中数字磁罗盘这一姿态传感器所产生的误差进行补偿研究。在深入分析全姿态误差补偿原理的基础上,针对其补偿局限性提出了一种基于地磁分量的误差优化补偿方法。构建了新的误差补偿框架,通过粒子群搜索算法对非线性因子进行估算。设计了磁罗盘误差补偿试验。试验证明,基于地磁分量的误差优化补偿方法有效提升了航向测量精度,其提升幅度为10%~20%。该方法在现场校正数字磁罗盘过程中具有较大的应用价值。In order to improve the measurement accuracy of an embedded integrated optoelectronic aiming system,an error compensation method of the key component digital magnetic compass in the system was studied.On the basis of in-depth analysis of the principle of full attitude error compensation,a method of error optimization compensation based on geomagnetic components was proposed to address its compensation limitations.A new error compensation framework has been constructed to estimate nonlinear factors through the particle swarm search algorithm.A magnetic compass error compensation experiment was designed.Experimental results have shown that the error optimization compensation method based on geomagnetic components effectively improves the accuracy of heading measurement,with an improvement range of 10%to 20%.This method has significant application value in on-site calibration of digital magnetic compasses.
