摘要:
采用最小二乘法估计速度和加速度,通过引入机动检测,动态调整有限记忆的点数,在速度估计上,既保证直飞段的平稳,又减小转弯段的滞后,从而实现空中目标航迹自适应跟踪.对位置采用一步滤波估计,在位置滤波上,提出一种由状态信息进行滚转角预测的方法,并将滚转角引入到卡尔曼滤波参数的自适应修正上.仿真结果表明,采用该方法既能使直飞段很好地维持航迹平稳,又能在转弯段实现目标的快速跟踪.
Abstract:
A new adaptive tracking method for aerial targets is proposed. Velocity and acceleration are estimated by the limited memory of the least square method while position is estimated by a one-step filter. In the estimation course of velocity and acceleration,the dynamic number of limited memory dots is adjusted according to the result of maneuver detection in order to ensure the smooth tracking for straight flight and less lag for swerve. A roll angle prediction method is proposed in the position filter. The roll angle is used to adjust the parameters in the Kalman filter adaptively. Simulation results show that the target can be tracked smoothly in straight flight and rapidly in swerve flight.
