| 1. | Tracking target state with td
估计目标状态 |
| 2. | The methods about tracking target are introduced into two aspects which are gate tracking and correlative tracking
图像跟踪的方法则是从波门跟踪和相关跟踪两个方面作了介绍。 |
| 3. | Since 1930s radar was invented , it has been used in many fields , especially in military detect , capture and track targets
随着20世纪30年代雷达的出现以及在军事领域的大规模应用,波形产生一直成为雷达领域的重要研究内容。 |
| 4. | In both military and civilian fields , for instance , in air defense and in air traffic control , we all need tracking targets in a reliable and accurate mode
在军事和民用领域譬如空防和空中交通管制中,需要可靠而精确的跟踪目标。 |
| 5. | That the system can stably track targets at lake test shows the signal micro - structure extraction is effective and can be implemented for engineering application
在湖上试验中，该系统能稳定地跟踪水声目标，这说明信号微结构的提取方法是有效的，适合工程化应用。 |
| 6. | During the same period of tracking target , the immpdaf can manage radar too , such as adaptively selecting revisit time , detection threshold and radar waveform
这样的整个过程，使得在跟踪目标的同时，也参与了雷达的管理，譬如自适应的选择采样时间、探测门限、探测波形。 |
| 7. | In trajectory control , it is requested that the system not only can track target trajectory , but also is robust and has the ability of restrain interfering signals
在轨迹跟踪控制中，往往既要求系统能准确快速的跟踪目标轨迹，又要求系统具有一定的鲁棒性，及干扰抑制能力。 |
| 8. | The photoelectric theodolite ( abbr . pt ) is an important measure device for tracking target . the ability of pt , such as quick capture and stable tracking , is close related to real - time guide data
光电经纬仪是跟踪目标的重要测量设备，光电经纬仪快速捕获、稳定跟踪，与实时引导数据密切相关。 |
| 9. | It will produce very big angular velocity , angular acceleration and angular jerk when tracking fast moving targets . this may lead bigger tracking error and fail to track targets
目标速度的提高将会产生大的角速度、角加速度乃至更大的角加加速度，导致光电经纬仪电视跟踪动态误差急剧增大，目标逸出视场，跟踪失败。 |
| 10. | The author replaces the old polynomial motion model ca with a new nonlinear motion model further improving current statistical model , and the results are of better performance on tracking target
作者用一种具有恒法向和恒切向加速度的非线性的运动模型了进一步完善了“当前”统计模型,使滤波器对航迹的跟踪性能大大提高了。 |
