Space target visibility judgment method for sky-ground situation awareness system

The invention discloses a space target visibility judgment method for a space and foundation situation awareness system, and relates to the field of space situation awareness. Constructing a space-based situation awareness system detectability mathematical model and a foundation situation awareness system detectability mathematical model; according to the sky-foundation situation awareness system detection capability mathematical model, establishing a sky-foundation situation awareness system integrated detection capability mathematical model; obtaining judgment time, state parameters of a to-be-judged space target and layout and detection performance parameters of a space-based situation awareness system and a foundation situation awareness system; and based on the acquired data, solving the integrated detection capability mathematical model, and judging whether the space target is visible or not according to a solving result. According to the method, the detection capability of a space-based situation aware
