根据中远程导弹制导系统大都采用脉冲多卜勒雷达导引头的趋势和中远程防空导弹末制导实现对目标机动运动状态的需求,基于目标螺旋机动和蛇行机动的切向加速度和法向加速度在目标轨迹活动框架上缓变的特点,本文提出了一种建立在目标轨迹活动框架上的运动状态方程和自适应Kalman估计算法,该方法克服了在直角坐标系和球坐标系上估计目标快变加速度机动延迟大的缺陷。仿真实验证明该算法有很好的跟踪稳定性和收敛性,为先进末制导律的实现创造了条件。
根據中遠程導彈製導繫統大都採用脈遲多蔔勒雷達導引頭的趨勢和中遠程防空導彈末製導實現對目標機動運動狀態的需求,基于目標螺鏇機動和蛇行機動的切嚮加速度和法嚮加速度在目標軌跡活動框架上緩變的特點,本文提齣瞭一種建立在目標軌跡活動框架上的運動狀態方程和自適應Kalman估計算法,該方法剋服瞭在直角坐標繫和毬坐標繫上估計目標快變加速度機動延遲大的缺陷。倣真實驗證明該算法有很好的跟蹤穩定性和收斂性,為先進末製導律的實現創造瞭條件。

To meet the demand of terminal guidance of the medium-long range antiaircraft missile for target state, a new target state model and an adaptive Kalman estimating algorithm for radar homing missile attacking maneuvering target is proposed, with seeker radar adopted pulse doppler radar guidance system, based on the slowly changing of the tangential acceleration and the normal acceleration of the spiral maneuvering and snaking maneuvering in target trace frame coordinate system. It resolves the backward of long delay in fast-changed acceleration of target tracking in Cartesian coordinates or spherical coordinates. Simulation of one missile control and guide system proved its good stability and convergence, which will be very valuable for engineering accomplishing the advanced terminal guidance law.
