【摘要】：因傳統(tǒng)濾波跟蹤方法在精度和速度上難以兼得而不能滿足MIMO系統(tǒng)直接用于自動瞄準(zhǔn)射擊系統(tǒng)應(yīng)對高速多目標(biāo)捕獲跟蹤的需求。為此,文中提出一種適用于MIMO雷達系統(tǒng)的自適應(yīng)g-h-k濾波跟蹤瞄準(zhǔn)器。其主要原理是針對多目標(biāo)變加速運動,在構(gòu)建由位置增益、速度增益和加速度增益組成的變加速運動狀態(tài)模型的基礎(chǔ)上,提出并解算加加速度濾波方程,然后通過動態(tài)調(diào)節(jié)角度變量參數(shù),實現(xiàn)跟蹤誤差最小化。實踐表明,針對高機動運動目標(biāo),能很好解決MIMO雷達系統(tǒng)精度和收斂速度的矛盾問題。
[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.
