摘要
对于静止观测来说,由于测量器静止不动,得不到足够的目标信息,所以利用仅有角测量跟踪方法,无法实现对空中目标的有效跟踪.针对直升机巡航时的运动特征,提出一种用于反直升机智能雷的目标角度跟踪算法.基于被动声测量得到的目标角度信息,建立了三维坐标下角跟踪数学模型,以实现目标方位角和高低角的跟踪与预测.仿真结果表明,算法的跟踪和稳定性较好,预估值接近于真值,可为智能雷打击目标提供有力参考.
To static measuring, tracking targets in the air efficiently can not be realized by using the bearing-only tracking solution, because the detector is static and can not get enough information of target. Aiming at motion character of cruising helicopter, a target angle tracking solution in anti-helicopter mine (AHM) is presented in this paper. Based on target angle information obtained from passive acoustic measurement, the angle tracking mathematic model in trigonometric coordinates is developed, by using of which the azimuth of target can be tracked and forecasted. Results from simulation experiments demonstrate that tracking performance of this approach is better, and that foreseeable angle is close to the true value, which would be taken as strong reference for AHM hitting the target.
