顺序更新式无序量测处理算法
An Sequential Updating Algorithm for Out Of Sequence Measurement
摘要
Abstract
In the centralized multi-sensor target tracking systems, usually the measurements from the same target arrive at processing center out of sequence, that is, called out-of-sequence measurement problem. Inspired by the equivalent measurement and re-filtering method,a sequence processing algorithm for out-of-sequence measurement based on equivalent measurement is proposed. In that algorithm,an equivalent measurement is used to,replace the measurement sequence which needed to cache in re-filtering method, and then updates from the measured time of out-of-sequence measurement sequentially with the out-of-sequence measurement and equivalent measurement. Theoretical analysis and simulation results show that the algorithm is optimal when dealing with one step delay problem and is near optimal when dealing with multi-step delay problem. Also the algorithm has a small additional storage and a high filtering accuracy.关键词
