Then, the chaser ' s two orbit roots are selected as variable and visualizing the simulation by contour plot. this part of research draws the conclusion the same as the first part when the target ' s orbit is circular orbit, while the selected two variable can be wildly changed if the target ' s orbit is elliptical orbit. next, wait time before orbit maneuver is simulated
其次，利用可視化的等值線圖研究了追蹤器軌道兩個參數為變量的情況下大范圍軌道機動問題，分析表明對圓軌道目標器交會機動時，追蹤器軌道根數不宜與目標器軌道根數相差過大，而對橢圓軌道目標器交會機動時，追蹤器軌道根數可選范圍較大，機動策略和方法富於彈性。They are applied to different situations and verified by experiments. analysis model of small ap oblique penetrating ceramic / metal light armor is established on the basis of energy model and the assumption of ellipse absorbing the same energy in back plate, giving the predictable formula about ballistic limit velocity. with energy model the optimization design in relation to ceramic / metal light armor is analyzed and the optimal coefficient of ceramic / metal composite armor is gained
本文的主要研究內容如下： （一）建立了小型穿甲彈垂直侵徹陶瓷/金屬輕型裝甲的動量模型和能量模型，它們分別適用不同情況，並通過試驗驗證；基於能量模型和背板橢圓吸能相同假設，建立了小型穿甲彈斜侵徹陶瓷/金屬輕型裝甲的分析模型，給出了彈道極限速度預測公式；利用能量模型對陶瓷/金屬輕型裝甲的優化設計進行了分析，給出了陶瓷/金屬復合裝甲的最佳優化系數。The missile ’ s lunch point parameters and burnout point parameters are estimated using boost phase state estimation, and the impact point is predicted according to ellipse trajectory theory. and the effect of the estimation error of the burnout point on the impact estimate precision is analyzed
