Method for quickly selecting detection target of sun-earth equilibrium point asteroid

The invention discloses a method for quickly selecting a detection target of sun-earth equilibrium point asteroid, and belongs to the field of aerospace. The method includes the steps that a prober kinetic equation is established under the rotation system of sun-earth center of mass; the position velocity of the prober under the rotation system is converted to the inertial system centered on the sun, and is denoted as the orbital element form; the speed increment constraint and transfer time constraint of the prober are given, the optimal two-pulse transfer orbit is solved, and the maximum orbital root range of the constrained asteroid detection target is calculated; according to the range of target parameters of asteroid detection, the target of asteroid detection in the asteroid databaseis selected, and the target of asteroid detection outside the range of parameters is excluded; the remaining asteroid detection targets are targets of asteroid detection which meet multiple constraints, according to the requ
