【摘要】：因传统滤波跟踪方法在精度和速度上难以兼得而不能满足MIMO系统直接用于自动瞄准射击系统应对高速多目标捕获跟踪的需求。为此,文中提出一种适用于MIMO雷达系统的自适应g-h-k滤波跟踪瞄准器。其主要原理是针对多目标变加速运动,在构建由位置增益、速度增益和加速度增益组成的变加速运动状态模型的基础上,提出并解算加加速度滤波方程,然后通过动态调节角度变量参数,实现跟踪误差最小化。实践表明,针对高机动运动目标,能很好解决MIMO雷达系统精度和收敛速度的矛盾问题。
[Abstract]:Because the traditional filtering and tracking method is difficult to achieve both precision and speed, it can not meet the requirement that MIMO system is directly used in automatic aiming and shooting system to deal with high-speed multi-target capture and tracking. In this paper, an adaptive g-h-k filter tracking sight for MIMO radar system is proposed. On the basis of the variable acceleration state model composed of velocity gain and acceleration gain, the acceleration filtering equation is proposed and solved, and the tracking error is minimized by adjusting the angle variable parameters dynamically. For high maneuvering target, the contradiction between precision and convergence speed of MIMO radar system can be solved well.
