摘　　要：研究了单脉冲作用下动能型在轨拦截器的覆盖范围。针对初始轨道为圆轨道的情况,利用运动方程推导了在轨拦截器覆盖范围的球面坐标表述形式;针对初始轨道为椭圆轨道的情况,结合位置矢量和轨道根数描述方法的优势,利用运动方程及高斯摄动方程确定了在轨拦截器的覆盖范围及其表述形式。仿真结果表明,该方法能够简捷有效地描述在轨拦截器的覆盖范围,能够为在轨拦截器机动轨道设计及优化的前提判断提供技术支持和模型支撑。The coverage area of the kinetic orbit-interception with single-impulse was researcheO in tins paper. For the initial circular orbit, the authors derived the expression of spherical coordinates for the coverage area of the orbit-interception. For the initial elliptical orbit, the coverage area was ascertained by equations of motion and Gaussian perturbation equation based on consolidating the advantage of posi- tion vector and orbit element for describing the coverage area of the orbit-interception. The simulation re- suits verify the approach in this paper can describe the coverage area of the orbit-interception concisely and efficiently. The approach in this paper can provide technical and model support for conditions judg- ment which is the prerequisite for design and optimization of orbit-maneuver.
