The invention discloses a particle filter centralized tracking method for multi-base radar out-of-sequence measurement fusion, which belongs to the technical field of data fusion of multi-base radar systems. According to the invention, out-of-sequence measurement is sequentially used to update all states between the out-of-sequence measurement generation time and the latest sequential filter time,and particle filtering is used to achieve target tracking; the problem of deterioration of target fusion tracking performance, which is caused by radar measurement out-of-sequence caused by differentdata processing time of a radar station and communication link delay, is overcome; whether the current measurement is sequential measurement is judged; if the current measurement is sequential measurement, sequential measurement update is carried out, and otherwise out-of-sequence measurement fusion is carried out; the problem of out-of-sequence measurement of multiple arbitrary timing sequences,which is caused by different data preprocessing time of each radar station and communication link delay in a multi-base radar system is effectively solved; and a universal solution is proposed for the problem of out-of-sequence measurement of multiple arbitrary timing sequences, which has higher fusion precision than direct neglect of out-of-sequence measurement.
