Description

technical field [0001] The invention belongs to the technical field of target tracking, and relates to a radar and infrared sensor deployment method applied to target tracking. Background technique [0002] Target tracking is the process of estimating the state information of the target according to the data obtained by each sensor in the wireless sensor network (WSN). With the development of multi-source information fusion technology, it has been proved that multiple heterogeneous sensors can track targets simultaneously with higher tracking accuracy than using a single sensor. The main techniques for tracking using multi-source information fusion are: extended Kalman filter, unscented Kalman filter, etc. Sensors commonly used for tracking include radar and infrared sensors. In actual target tracking, it is difficult to ensure that each target can be detected by multiple heterogeneous sensors. Under normal circumstances, it can be detected by multiple heterogeneous sensor...
