摘要
在纯方位目标跟踪定位研究领域里 ,采用极坐标模型 ,可以实现可观测状态和不可观测状态的分离 ,但非线性的系统方程使算法的具体实现非常困难。利用状态空间的变换 ,可避免直接计算非线性函数雅可比矩阵的值 ,减小了计算量 。
In the Bearings-only target tracking localization research area, using the polar coordinate model, we can realize the separation of observable state and the unobservable state, but the non-linear system equation causes the realization of algorithm to be extremely diffecult. Using the state space transformation, we can avoid the direct calculation nonlinear function and the value of Jacob matrix, and we can reduce the computation quantity and enhance the stability of filter.
