Earliest arrival and shortest avoidance method for anti-satellite reconnaissance in road maneuvering

Abstract

The invention discloses an earliest arrival and shortest avoidance method for anti-satellite reconnaissance in road maneuvering, which realizes avoidance of a moving vehicle to multi-satellite reconnaissance under a fixed moving route. When an anti-satellite reconnaissance avoidance action strategy is formulated, two elements needing to be focused are arrival time and avoidance duration respectively. According to the method, an earliest arrival strategy generally needs to be selected under the condition of an emergency task, 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, so that missed alarms possibly caused by spaceflight reconnaissance avoidance calculation only carried out on important point locations are avoided, and the risk of spaceflight reconnaissance avoidance calculation is reduced. And low efficiency caused by calculation of the whole area through which the route passes is also avoided. Compared with the prior art of only outputting the starting and ending time of the safety window, 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 a method for the earliest arrival and shortest avoidance of anti-satellite reconnaissance in road maneuvering. Background technique [0002] The current space reconnaissance avoidance algorithm is mainly calculated for fixed points or areas, and the space reconnaissance avoidance algorithm for the action line is not mature. For example, the STK software of the American AGI laboratory can carry out spacecraft reconnaissance and forecasting on the route, but it can only calculate the maneuvering actions of vehicles departing at a certain time. When a certain unit in China provides satellite reconnaissance and forecast services for action routes to user units, it only converts the space reconnaissance and avoidance calculation of the action route into the space reconnaissance and avoidance calculation of the route passing area or conducts full-time calculation of som...

AI Technical Summary

Problems solved by technology

[0003] 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.
