空间目标可拦截区与可遭遇区的确定

Determination of Interceptable Section and Encounter Section for Space Target

给出了天基拦截器对空间在轨目标的可遭遇区、可拦截区和实际可遭遇区的定义,基于冲量变轨理论,并以真近点角表示这三个区域,给出了确定这三个区域的数值搜索算法。对于非机动轨道目标,训练好的BP神经网络可根据拦截器/目标的相对位置,快速给出目标轨道上的可拦截区和实际可遭遇区。

This paper proposes the conception and definition of encounter section, interceptable section and real encounter section when a space-based interceptor attacks a space target. Based on impulse orbit-transfer theory, numerical methods are presented to determine these sections which are described with true anomaly. For a non-maneuvering orbital target, the trained BP-NN can output interceptable/real encounter section quickly according to the relative position of interceptor and target.
