摘　　要：纯方位定位方法因其测量实现较为简单,在低成本定位系统应用方面前景广阔。针对动态目标定位这一研究热点,从方位测量方法、动态目标运动模型、滤波估计算法方面对近年文献的研究现状进行了总结,并阐述了相关原理。方位测量方面,重点分析了光学测量和无线电测量;动态目标模型方面,在运动模型建模的基础上讨论了多模型算法;滤波估计算法方面,针对测量模型的非线性、噪声特性不准确、非高斯白噪声、测量值异常四个问题,阐述了目前的研究成果。最后探讨了纯方位定位的发展趋势。Because the bearings-only tracking measurement is simple to implement,it has broad prospects in the application of a low-cost positioning system.Aiming at the active research area of maneuvering target tracking,the literature on bearing measuring method,maneuvering target motion model and filter algorithm are summarized,and the relative principles are concluded.For bearing measuring method,optical measurement and radio measurement are discussed.For maneuvering target motion model,the multiple-model algorithm is discussed on the basis of motion modeling.For filter algorithm,the research results are concluded from four aspects,which are nonlinearity of measurement model,inaccurate noise statistics,non-Gaussian white noise and measurement outliers.Finally,the future trends for bearings-only tracking are discussed.
