Abstract

NEOs have the characteristics of inconspicuous target features,uncertain orbital period,and difficult to discover and predict.In recent years,with the continuous development of aerospace technology,problems such as the risk analysis of NEOs impacting the Earth and their disposal on orbit have become a research hotspot in the field of space science.The mode of intercepting and deflecting NEOs by kinetic impactor is an effective approach of on-orbit emergency disposal.In this paper,the research on these problems is carried out,and a target recognition and guidance control scheme is proposed.The centroid positioning method based on edge extraction is used to determine the target line of sight vector,and the advanced proportional guidance law is used to achieve accurate impact on the target,and a hardware-in-the-loop simulation platform is built.The effectiveness of target recognition algorithm and guidance control algorithm is verified and evaluated.

Key words： near-Earth object; kinetic impact; GNC system
