摘要:
针对临近空间高动态飞行器的角度捕获引导问题,从馈源多波束引导与传统引导存在的差异入手,引入一次检测概率与持续检测概率的概念,并结合分组切换影响,设计给出馈源多波束系统引导概率分析方法。分析得出馈源多波束系统的四次引导概率能够超过99.5%,满足任务要求。该分析方法及给出的结论为Ka频段馈源多波束引导自跟踪的工程建设提供技术支持。

Abstract:
To implement the acquisition and guidance of near-space high dynamic spacecraft,beginning with the differences between the multi-beam parabolic antenna and the traditional coaxial antenna,the concept of one-time detection probability and continuous detection probability are introduced,as well as division switch factor,and the method for calculating the guiding probability of Ka-band multi-beam parabolic antenna is proposed in this paper.The analytic results show that the guiding probabilities of four-time guidance process are over 99.5% which meets the project requirement.The method and conclusion provide technical supports for construction of the multi-beam parabolic antenna telemetry and tracking system.
