The invention relates to the technical field of space target collision early warning, and discloses a distribution-based space target collision early warning method, which comprises the following steps: S1, space target preliminary screening: performing preliminary screening on space targets based on three steps of epoch time, perigee, apogee and minimum distance; s2, accurately screening the space targets, and further screening the space targets discharged in the step S1; and S3, performing orbit forecasting and early warning calculation, and performing space target collision early warning calculation based on the orbit data of the space target and the corresponding orbit forecasting model. According to the characteristics of space flight of the spacecraft and the space debris, the invention provides a method for calculating the collision early warning of the space target by combining osculating elements and TLE elements. According to the multi-screening space target collision early warning algorithm of the two-body model and the SGP4/SDP4 model, the effectiveness and the accuracy of the early warning algorithm are proved through simulation, and the early warning efficiency and the early warning time of collision between the spacecraft and the space debris target are improved.
