The invention discloses a space debris collision early warning method, which is characterized by comprising a space debris positioning system and an early warning system; the early warning system is used for calculating the relative motion trail of space debris under a spacecraft orbit coordinate system by utilizing spacecraft orbit information through space debris observation information detectedby a microwave radar on a spacecraft, calculating the minimum distance of the space debris relative to the spacecraft in the future T time, giving early warning information by judging the minimum distance for multiple times, and starting an orbit avoidance program for avoiding collision. Compared with the prior art, the invention aims to provide the space debris collision early warning method, which is provided for the collision harm of the space debris to the satellite, has a good actual processing effect, and can be widely applied to space debris monitoring.

    本发明公开了一种空间碎片碰撞预警方法,其特征在于,空间碎片定位系统和预警系统;其中,所述预警系统:通过航天器上微波雷达探测到的空间碎片观测信息,利用航天器轨道信息,计算空间碎片在航天器轨道坐标系下的相对运动轨迹,并计算未来T时间内的空间碎片相对航天器的最小距离,通过多次对最小距离的判断,给出预警信息,并启动躲避碰撞的轨道规避程序。与现有技术相比,本发明的目的在于提供一种空间碎片碰撞预警方法,针对空间碎片对卫星的撞击危害而提出的,该方法的实际处理效果好,能够广泛地应用到空间碎片监测中。
