| 摘 要： | 本文讨论在修正极坐标下利用推广卡尔曼滤波实现纯方位目标跟踪的具体方法。通过采用协方差平方根滤波与变系数衰减记忆滤波,克服了跟踪过程中的计算发散和滤波发散,获得了比较满意的稳定和渐近无偏的估计结果,并利用Z80-CPU配接适当的外部设备实现了实时的跟踪处理。此外,还对纯方位目标跟踪的一些性质进行了分析。

| Abstract: | With a modified polar coordinate, a specific method to realize bearings-only target tracking by means of an extended Kalman filter is discussed in this paper. By using a covariance square root filtering and a fading memory filtering with variable coefficient, the defect of computation and filtering divergence can be overcomed, and a stable and asymptotically unbiased estimation is obtained satisfactorily. Besides, the real time tracking processing can be achieved by Z80-CPU with proper external equipments. Some performance of this target tracking is also analyzed. |
