基于双智能雷的目标跟踪方法研究

目前被动声探测距离精度还不能满足跟踪的需要，因此，反直升机智能雷对目标的跟踪问题归结为仅有角测量的跟踪问题。对于静止观测来说，仅有角测量跟踪问题是不可观测的。针对直升机巡航时的运动特征，提出一种基于双智能雷的目标跟踪方法。首先用角跟踪算法实现目标方位角和高低角的跟踪和预测。然后融合目标在两智能雷坐标系下的角度信息，建立数学模型，解算出目标的距离和速度大小。仿真结果表明，算法的跟踪和稳定性较好，能对目标的距离、方位角、俯仰角和速度大小进行有效的跟踪和预估。

Approach to Tracking Target Based on Double AHMS

Tracking target by using anti-helicopter mine(AHM) is actually the bearing-only measurement because precision of range detected by passive acoustic measurement can't satisfy the need of tracking.To static measuring,bearing-only measurement tracking can't be completed.Aiming at the motion character of cruising helicopter,an approach to track target based on double AHMS is presented in this paper.At first,the prediction of target angle information is made by the approach to tracking angle,then the target angle information is fused.Finally the mathematic model is set up and the target speed and range are computed.Results from simulation experiments demonstrate that the method is reliable and efficiency,it can be used to track and predict target range,bearing,pitch and speed.
