| 摘 要： | 干扰对组网雷达目标跟踪系统模型的影响,决定了系统需要用非线性滤波技术进行纯方位跟踪.粒子滤波避免了传统非线性滤波方法的缺陷,但是存在粒子退化,于是用EKF和UKF在每一时刻更新粒子,用更新的粒子及其协方差构造重要性函数,然后重采样.仿真实验表明了这两种改进粒子滤波方法的有效性.

| Abstract: | The radar networked target tracking system using non-linear filtering for bearings-only tracking is determined by the jamming.The particle filtering avoids the shortage of traditional non-linear filtering,but particles degradation exists.So EKF and UKF are used to improve the particle filtering.Simulation results show that the new algorithm is more effective. |
