基于跟踪精度控制的传感器管理方法研究

Study on methods of sensor management based on tracking accuracy control

军用多传感器系统往往需要在保证完成任务的同时,尽可能地隐蔽自己,为此要求传感器管理系统必须能够在满足跟踪精度要求的前提下,最大限度地降低对资源的使用,特别是减少主动传感器的开机时间。基于该目的,讨论了一种基于跟踪精度控制的传感器管理方法,该方法利用协方差控制技术,保证系统在满足给定性能指标的前提下,对传感器资源的利用最少,从而提高了系统的抗毁性。同时对给定精度过高,造成的系统无解情况给出了一种解决方案,并通过对一个单目标跟踪场景的仿真,验证了该方法的有效性。

It is often necessary for many military multi-sensor systems to implement the given mission while trying to keep hidden. Accordingly, for multi-sensor fusion tracking systems, the sensor management systems must minimize the use of resources, especially the working time of active sensors while ensure the tracking accuracy. Based on the considerations mentioned above, a multi-sensor management method based on target estimate covariance is discussed. It can maintain a desired covariance level with the least use of sensors. And an improved approach is given to solve the problem that no solution will be get when the desired covariance can't be met. Simulation for single target tracking scenario has been made and the result proved the effectiveness of the method.
