| 研究了角度和频率变化率量测下的单站目标运动分析的可观测性。分别基于相容轨迹法和系统可观测性理论进行了可观测性的定性和定量分析，两种方法相互印证。通过分析指出，有限阶目标运动下，目标运动分析可观测的充要条件是目标与观测平台间存在非径向运动。仿真结果验证了理论分析结论的正确性。 |

| Abstract: |
| The target motion analysis(TMA) observability using angle and frequency rate measurements is presented.The observability is analyzed by using the Compatible Locus Method and the System Observability Theory,respectively.The results of the two methods are verified by each other.It is concluded that the TMA is observable when the target conducts finite-order movement if and only if the relative motion between the target and the observer is not radial.Simulations verify the correctness of theoretical analysis conclusion. |
