中文摘要：
激光陀螺误差决定了机载全成孔径雷达（SAR）运动补偿用位置姿态测量系统（POS）的测量精度。针对激光陀螺测量精度受环境温度影响严重的问题进行了研究，分析了激光陀螺的温度误差模型，结合支持向量机SVM的函数拟合功能，提出一种新的陀螺温度误差建模与补偿方法。与基于线性回归以及神经网络的补偿方法相比，该方法具有精度高、泛化能力强等优点。实验结果表明，激光陀螺的温度误差减小约75％，提高了激光陀螺对环境温度的适应能力。
英文摘要：
Laser gyroscope error determines the measurement accuracy of position and orientation system （POS） used for airborne SAR motion compensation. The problem of the severe influence of environmental temperature on laser gy- roscope measurement accuracy is studied;the temperature error mathematical model of laser gyroscope is analyzed. Based on the function fitting capability of support vector machine （SVM）, a new modeling and compensation method for gyroscope temperature error is proposed. Compared with the compensation methods based on linear regression or neural network, the new method has the advantages of higher precision and generalization performance. Experiment results demonstrate that the proposed method could decrease the temperature error of laser gyroscope by 75% and promote its adaptability of laser gyroscope towards environmental temperature.
