一种红外搜索系统的分布式多传感器航迹融合算法

红外搜索系统作为被动式搜索系统，一般只能获得目标所处位置的方位角和俯仰角信息，缺乏距离信息，在无测距装置的条件下，只能依靠角度信息进行数据融合。依据角度值的三角函数关系，提出了一种新的分布式多传感器航迹加权融合算法，算法经仿真验证有效，降低了融合航迹的误差。在对量测数据进行误差修正的基础上，算法效果更加显著。

Distributed Multi-Sensor Track Fusion Algorithm for IRST

IRST is a passive system. It can only get the elevation and the azimuth angle information without distance information. If there are no devices for measuring distance, the track fusion only can be carried out by using angle information. A new distributed track fusion algorithm is presented, which uses the correlation of the angle trigonometric function. The simulation results prove that the algorithm is available and can decrease the error of fusion track. On t he basis of modified measurement angle value, it can get better effect.
