Based on the virtual target point and the ellipse trajectory theory, a new maneuver method in the free - flight phase is presented.
基于虚拟目标点和椭圆弹道理论，提出了一种在自由段机动变轨的新方法。
A back and forward filter with steeper transitional band was designed of ellipse function. It can remove nonlinear phase distortion caused by IIR filter.
利用椭圆函数滤波器较陡的过渡带特性设计前向和后向滤波器，消除由于IIR滤波器造成滤波后的数据相位非线性失真。
