摘要
针对传统定位系统和测速仪不能同时提供动目标的位置、速度和方位的问题,提出了一种基于到达时间差定位技术的动目标跟踪的速度和方位等状态信息获取方法。该方法利用动目标连续定位位置及目标发出信号的时间间隔,得到动目标的速度和方位信息,仿真数据分析结果表明了该方法的有效性。
In view of the tradition localization system and the velocimeter cannot simultaneously provide the position, the speed and the azimuth of the movement target, proposed one kind of movement target tracking speed and position state obtaining methods based on the time difference of arrival localization technology. This method use the localization position of movement target and the time interval of target eontinuously sending out the signal to obtain its speed and the azimuth information. The simulation data analysis result has indicated this method validity.
