基于倾斜角的多目标测向无源定位技术

Multi-Target Bearings-only Passive Location Technology and Tracking Based on Inclination Angle

摘要:

对多目标测向无源定位问题进行了研究。虽然无源观测站不同,针对同一目标的方位角和俯仰角数据也不同,但它们有共同的倾斜角。基于此,提出了基于倾斜角的多目标测向无源定位算法。该算法分别计算一组与多个目标对应的倾斜角,然后利用倾斜角最接近原则对这2组数据进行关联判断,解决多目标测向数据的关联和定位问题,并通过仿真实验,对算法的有效性和可行性进行了验证。

Abstract:

In this paper, the problem of multi-target bearings-only passive location and tracking was studied. Though the bearings and pitch angles were different from different passive sensors for the same target, but the inclination angle was the same one. So the multi-target bearings-only passive location and tracking algorithm based on inclination angle was presented. This algorithm calculated a set of inclination angles for multi-target when the sensor at the origin of coordinate, and then associated the two sets data using the inclination angle nearest principle. It resolved the problem of target bearing data association and location.At last, the effectiveness and feasibility of the algorithm was tested using computer simulation.
