circular target
解釋
圓形目標-
The complex nonlinear pursuit - evasion model of two spacecraft in near - earth coplanar orbit is simplified to linear model, the circular region the radius of which is equal to capture radius is defined as target set, capture is achieved when the evader come into the target set and the game is over ; the boundary of useable part ( bup ) is determined, and the analytical form solution of the linear equations is obtained by backward integration of the state variables from the bup, the linear barrier of the pursuit - evasion model and the optimum thrust of the both sides are thus obtained
本文將近地共面軌道內運動的兩飛行器非線性追逃模型簡化為線性模型，以捕獲半徑的圓域定為目標集，確定目標集邊界上的可用部分，並以此為各狀態變量的起點，對時間進行倒向積分，求得線性方程組的解析解，從而確定了該追逃模型的線性界柵，以及界柵上對策雙方的最優推力，即求得了滿足最優策略時相對運動的軌跡和推力。 -
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。 -
