Rapid calculation method for satellite reconnaissance coverage area target

The invention discloses a rapid calculation method for a satellite reconnaissance coverage area target. The rapid calculation method comprises the following steps: carrying out primary screening on a satellite coverage calculation range by utilizing a satellite maximum radius distance RSateMaxAngle and a maximum edge distance maxR; performing secondary screening on the satellite coverage calculation range by using the angle ZOP, the angle ZOA and the angle POP '; performing third screening on the satellite coverage calculation range by using the target polygon and the satellite polygon; according to the method, the satellite coverage calculation range is subjected to primary screening, secondary screening and tertiary screening for a large-area regional target, the satellite coverage calculation range is greatly reduced when the regional target is calculated and analyzed, the satellite coverage calculation range is enabled to have purposiveness, and the calculation accuracy of the satellite coverage calculati
