摘要：
A stealth aircraft is constructed by Non-Uniform Rational B-Splines(NURBS), which surface can be controlled flexibly by changing the parameters of curves. By selecting the control point coordinates of NURBS reasonably, the aircraft structure is made up of only two surfaces. Therefore, the calculation amount of electromagnetic simulation is reduced. Then, the method of changing the weight with iterations is used to solve the limitation that the traditional optimization algorithm is easy to converge to the boundary. The RCS of aircraft is further reduced by using the improved optimization algorithm from -25.86dBsm to -38.86dBsm.
