| 中文摘要: |
| 目标运动分析是声纳的一个重要问题,并经过了30多年的认真研究。目标运动分析是建立在从目标信号中提取出的测度的基础上的。不同的测度会引入不同的问题,并有不同的优缺点。因而,目标运动分析可以用从目标信号中提取出的测度来刻画。目标运动分析的特点之一就是在某些态势下目标时不可观测的。为了能够有效地提取出目标参数,选择合适的测度集合和最佳观测者机动至关重要。本文详细讨论了目标运动分析问题的测度、可观测性和最佳观察者机动问题。 |
| 英文摘要: |
| Target motion analysis(TMA) is an important problem for sonar, and this problem has been intensively studied over 30 years. TMA is based on the measurements extracted from the target signals. So the type and quality of the measurements are crucial points. Different types induce qualitatively different problems and have different advantages and disadvantages. Thus the TMA problem can be characterized by the type of measurement extracted from the target signal. A peculiarity of TMA is the fact that the target may not be observable from the used set in some situation. In order to extracted target states more effectively, choosing appropriately measurement set and optimal platform maneuver are crucial points. The TMA problem about measurement, observability and optimal observer maneuver are discussed in detail in this paper. |
