Based on the scattering characteristic. the comparison of RCS (radar cross-section) at different positions of a target in the same direction of incidence can be obtained first by extruding or deleting part of the entity. A simulation method of aerial&space targets echo characteristics (A&STEC) is proposed that is universal to aerial and space targets. We utilize a fixed-wing UAV (unma... https://www.spidertattooz.com/Lander-3-Knife/
