Abstract:

For target tracking problem with emission constraints, an airborne radar/infrared search and track (IRST)/electronic support measure (ESM) synergistic tracking and management method is proposed. Since the measurements of radar/IRST/ESM are not coming at the same time, sequential centralized multisensor fusion algorithm is chosen for target tracking, the comparison of the predicted covariance and the given threshold is used to decide the radar to radiate, and the relation between radar’s radiation time with different IRST/ESM intermissions and different thresholds is analyzed. The research conclusion can help to increase the combat aircraft’s concealment capacity and survival capacity.
