Embodiment Construction

[0018] refer to figure 1 . According to the present invention, the multi-sensor cooperative tracking system first needs to calculate the fusion tracking error of the multi-sensor cooperative tracking to the target, and the tracking and positioning error of the local radiation source being detected by the opponent's aircraft; In the process of fusion tracking error, the multi-sensor cooperative tracking system predicts the radar sensor target position information, the infrared sensor target position information and the multi-sensor fusion measurement information in the decision cycle, and fuses the radar sensor, infrared sensor and multi-sensor. Obtain the fusion measurement state and its fusion measurement covariance at the time of the decision-making cycle, and use the multi-source data fusion algorithm to calculate the fusion tracking error of the multi-sensor cooperative tracking to the target; in the multi-sensor cooperative tracking system, it is estimated that the radiat...
