The coilgun has important application prospect in space navigation and national defense, but the position of the projectile is difficult to decide. BRDF (bidirectional reflectance distribution function) perfectly describes the hemispherical spatial reflected characteristics and scattering characteristics of material surfaces. The application of BRDF on measuring projectile position in multi-stage...
