IMM Data Fusion Algorithm for Active/Passive Radars Based on UKF
Mao Yunxiang · Electronic Information Warfare Technology · 2011
A data fusion algorithm using IMM-UKF is presented based on active/passive radar target tracking.The algorithm is established in terms of IMM(interacting multiple model) and UKF(unscented Kalman filter).UKF is introduced to obtain the state estimation to avoid the EKF's disadvantage of dependence on initial value and divergence.Compared with single sensor,it is shown that the approach possesses better stability and higher locating precision.
