【摘要】:可观测性分析是建立系统误差估计模型的一个必要前提。针对二维平面中系统误差与目标状态联合估计模型的可观测性问题,采用可观测矩阵研究系统的可观测性。文中先建立了二维平面内目标的运动模型以及雷达的观测模型,同时构建了系统可观测矩阵,通过判定可观测矩阵的奇异性研究了系统的可观测性问题,并且给出了可观测度的Maple计算程序。最后,建立了典型的仿真环境,通过仿真分析了有无传感器量测误差情况下系统误差的可观测性及可观测度的特点。
[Abstract]:Observability analysis is a necessary prerequisite for the establishment of a systematic error estimation model. Aiming at the observability of the joint estimation model of system error and target state in two-dimensional plane, the observability of the system is studied by using observable matrix. In this paper, the motion model of the target in the two-dimensional plane and the observation model of the radar are established. At the same time, the observable matrix of the system is constructed, and the observability of the system is studied by judging the singularity of the observable matrix. The Maple program of observable measure is given. Finally, a typical simulation environment is established, and the observability and observability of the system error in the case of sensor measurement error are analyzed by simulation.
