    • Abstract
  • The trait of sphere target is analyzed,the generating process and characteristic of spherical center error are described by laser radar equation.The distribution of spherical center error with laser incident direction is researched and counted,and then determined by polynomial fitting model and simulation of sphere surface.The systematic characteristic of spherical center error is verified by the measured data and a weakening method is proposed.
