Study on the influence of Rocket booster to radar observation

On the possible influence of Rocket 2nd booster or debris (i.e., by-product of the separation) to radar observation, the concept of ROIO (Radar Overlapped Image Orbit) is introduced. In this paper, the geometry between the radar location and the trajectory plane are described, the orbit determination method of ROIO in space is also proposed, the case of two or more radars is discussed and the influence caused by the earth’s rotation is analyzed as well. Simulation results indicate that the influence is neglectable; the original orbit’s ROIOs are determined by radar observation range and the geometry between the radar’s location and the trajectory plane. Finally, some recommendations are presented on how to avoid ROIOs to affect the determination of the target’s orbit.
