摘　　要：为提高导弹位标器快速跟踪能力,提出一种以球面并联机构为稳定平台的新型位标器,研究其完整跟踪过程模型和算法。基于插值多项式建立了目标运动预测模型,基于向量几何法建立了位标器跟踪过程的电机运动求解模型,讨论了干扰振幅和频率对跟踪算法的影响。算例分析验证了新型位标器目标跟踪算法的有效性。该跟踪算法可满足实际情况下新型位标器的目标跟踪需要。In order to improve tracking performance of the missile seekers, a complete tracking algorithm is developed for a new missile seeker with a gyro stabilization platform based on spherical parallel mechanism. A trajectory prediction model is built for tracing moving targets by introducing interpolation polynomial. Then the angular motions of the two actuating links/servomotors are calculated based on inverse kinematics of spherical parallel mechanisms. Further the effect of disturbances on tracing accuracy is discussed in terms of amplitude and frequency. Examples demonstrated the presented tracking algorithm that is able to satisfy tracing requirement in real applications.
