摘要
由于粒子滤波的算法原理,其计算量很大。研究了针对机动目标的交互式多模型粒子滤波器(IMMPF)算法和多速率交互式多模型(MRIMM)算法,提出了多速率交互式多模型粒子滤波器(MRIMMPF)算法。该算法是在交互式多模型粒子滤波器(IMMPF)的基础上引入多速率技术,期望在保持IMMPF的性能同时能够减少因为粒子滤波带来的计算量;最后通过和一般基于EKF的IMM算法、IMMPF算法的比较,验证了该算法的有效性。
The algorithm of particle filter has an expensive computation because of its principle, the algorithm of IMMPF and MRIMM for the maneuvering target is studied, and the algorithms of Multi-rate Interacting Multiple Model Particle Filter（MRIMMPF） is proposed. The MRIMMPF, to which the multi-rate technique is introduced based on the IMMPF algorithm, is hoped to keep the performance of the IMMPF with less computation. Finally, the comparison experiment with IMM based on EKF, IMMPF demonstrates the validity of the MRIMMPF algorithm.
