Asynchronous bearing only tracking management approach in distributed multi-function integrated sensors

For multi-platform bearings-only cross location and tracking problem in distributed multi-function sensors, a target tracking management method based on asynchronous bearing only is proposed. The distributed multi-function system requires only one integrated sensor to switch to electronic support measure (ESM) mode within each tracking cycle to update the angle measurement information of target radiation source, while the other integrated sensors still work in the original planned mode and task. Compared with traditional cross location tracking method, the proposed asynchronous bearing only tracking method can improve the capability of the distributed integrated system with multiple functions such as reconnaissance, jamming and active detection at the same time in order to cope with the complex combat environment.
