摘要: 提出深度优化粒子滤波(DIPF:Deep Improved Particle Filtering)算法,从权值增长趋势和权值大小的综合比较进行样本的优化选择,通过对样本的统计分析确定样本的复制与裂变,虽然深度优化由于趋势判断增加了滤波时间,但是它克服了样本枯竭问题,提高了估计的精度.

关键词: 非线性滤波, 深度优化粒子滤波, 权值分析, 样本枯竭, 权值退化

Abstract: We present a deep improved particle filtering theory which selects samples from comparison of both weight increasing trend and weight.It decides fission and reproduction of samples through statistic analysis of samples.Though approaches increase computing time for trend judging,computing accuracy is improved.

Key words: non-linear filtering, deep improved particle filtering, weight analyzing, sample degeneration, weight degeneracy
