| 摘 要： | 针对运载火箭二级助推器及分离时产生的大的碎片对雷达观测可能造成的影响,阐述了雷达成像重叠轨道(ROIO)的概念,并就雷达处于火箭载荷轨道平面内的情况分析了ROIO的存在条件、确定方法和观测中火箭载荷轨道及其ROIO上所对应的位置相对于雷达的角度差.仿真结果表明,目标轨道的观测范围及雷达相对于该观测范围的距离决定了ROIO的确定.

| Abstract: | On the potential influence of Rocket's 2nd booster and debris on radar observation,the concept of the Radar Overlapped Image Orbit(ROIO) is introduced.In the case of the radar in the orbit plane,the preconditions for determination of ROIOs are analyzed.The radar imaging angle differences of the corresponding locations on the original orbit and its ROIOs are also proposed in this paper.Simulation results indicate that,the observation region on the target's orbit and the distance from the radar to the region ... |
