Anti-satellite reconnaissance safe action method for earliest arrival in road action

Abstract

The invention discloses an anti-satellite reconnaissance safe action method for the earliest arrival in a road action, which realizes the avoidance of multi-satellite reconnaissance by a moving vehicle under a fixed action route. When a strategy of anti-satellite reconnaissance avoidance safety action is formulated, two elements needing to be focused are arrival time and avoidance duration respectively. An earliest arrival strategy generally needs to be selected under the condition of task emergency, and when enough redundant time exists and the requirement for safety is high, a task party can select a strategy with the shortest avoidance duration on a road. Missed alarms possibly caused by spaceflight reconnaissance avoidance calculation only carried out on important point locations are avoided, and low efficiency caused by the calculation of the whole area through which the route passes is also avoided. Compared with the prior art that only the starting and ending time of the safety window is output, the method is more visual. Effective reference and support can be provided for spaceflight reconnaissance avoidance and action strategy planning of vehicle actions, and the method has high practical value.

Description

technical field [0001] The invention relates to the field of aerospace measurement and control, in particular to an anti-satellite reconnaissance safety operation method that arrives the earliest in road operations. Background technique [0002] Since the Gulf War, reconnaissance satellites have been an important means for countries to secretly acquire other countries. According to the UCS (Union of Concerned Scientists) satellite database released by the United States and other related webpages and documents, there are currently nearly 400 reconnaissance satellites from other countries operating in low orbits, of which no less than 100 satellites have a resolution better than 1 meter. With the development of the international aerospace industry, the number of low-orbit reconnaissance satellites will continue to increase. At present, road operations such as equipment transfers, troop changes, or important national material transportation are all major national secrets. In o...

AI Technical Summary

Problems solved by technology

The above algorithms all have problems such as low efficiency and high false alarm rate.

At the same time, the results generated by the above algorithm are mainly the start time and end time of the safety window, which cannot provide suggestions for road action strategies, lack of guiding significance for the action itself, and the practical effect is not obvious

[0004] To sum up, there is currently no set of anti-satellite reconnaissance security action strategies for vehicles / convoys traveling along a fixed route in China.
