| 摘 要： | 为精确计算飞行器在飞行过程中静电放电对雷达散射截面(radar cross section, RCS)的影响，采用高频电磁仿真软件Ansoft HFSS与物理光学(physic-optics, PO)法相混合。用HFSS计算放电产生的等离子体所覆盖的局部机翼的散射场，用物理光学法计算飞行器其余部分引起的散射场，将二者的等相位面重合，保持飞行器各散射体之间的相位关系，进而计算出飞行器的宽带雷达散射截面。

| Abstract: | The physic-optics (PO) method is combined with the electromagnetic software Ansoft HFSS to calculate accurately the radar cross section (RCS) of aircraft electrostatic discharging. HFSS is applied to compute the scattered field of the part which is covered with plasma, while PO is used for the other of the aircraft. The common constant phase front of two scattered fields is chosen to unify their phases, and the aircraft’s RCS can be exactly calculated. |
