Maneuvering target tracking, data association and distributed track fusion, three of the most important and general problems in target tracking area, are discussed in this dissertation 本文的研究内容包括机动目标跟踪、数据关联以及分布式航迹融合,是目标跟踪领域最具普遍性和重要性的三个问题。
The capacitance offset averaging network is used in the distributed track-and-hold circuit block of the designed system . finally, according to the analysis on error effects in adc, the mathematics error model is simulated . furthermore, the input-output characteristics including input- 最后,基于对a/d转换器系统中误差的分析,对其误差数学模型进行了仿真,得到了包含延迟、限幅、谐波失真等误差的输入输出特性曲线。
Furthermore, utilizing the characteristic that filtering error covariance expresses filtering precision and the principle of information conservation, the dynamic and reasonable distribution of distributed tracks weight coefficient is accomplished . jerk model and strong tracking filter is organically assembled, and based on spatio-temporal synthetically analysis and lme, a self-learning estimation method of the system measurement variance is given . the method improves obviously the 3、将jerk模型与强跟踪滤波算法有机地结合,并利用时空综合分析和极大似然估计的思想推导出了一种系统量测方差自学习修正方法,以优化强跟踪滤波算法中次优渐消因子和滤波增益的在线选择,同时根据多传感器数据融合具有改善滤波精度的性质,进而给出一种基于jerk模型的多传感器数据融合算法。
