基于IMMPF算法自适应驻留时间的控制与研究

Adaptive Dwell Time Control And Study Based on IMMPF Algorithm

为进一步提高雷达的目标跟踪性能,有效节省雷达的系统资源,在交互式多模型粒子滤波算法(IMMPF)的基础上,提出了一种自适应驻留时间设计方法。在满足一定跟踪精度的情况下,由信噪比、测量误差协方差与雷达驻留时间三者之间的关系,进一步研究分析交互多模型粒子滤波算法,通过改变雷达工作参数,完成了雷达驻留时间的自适应设计。通过仿真结果分析表明,提出的自适应驻留时间设计方法与固定驻留时间算法比较,在保证跟踪精度的同时,减少雷达系统资源的消耗,在实际雷达系统设计中具有一定的指导意义。

To further improve the target tracking performance of radar and save radar system resources, this paper puts forward an adap- tive dwell time design based on interactive multiple model particle filter （ IMMPF）. Under certain conditions of tracking accura- cy, this paper analyzes the multiple model particle filter , which realizes the adaptive dwell time design through changing operat- ing parameters of the radar. Simulation results show that comparing with the fixed dwell time algorithm, adaptive design meth- ods could ensure tracking accuracy, reduces consumption of radar system resource, which has a certain value in the actual ra- dar system design.
