摘要: 建立了在远距支援干扰和自卫或随队干扰下飞行器隐身性能计算方法.考虑的对抗情况是突防方用一架飞机进行远距支援干扰或者自己携带干扰机进行突防.通过算例计算了各种干扰及目标RCS对飞行器隐身性能的影响.结论是∶有效辐射功率为10kW的远距支援干扰可以大大减小飞行器的等概率探测范围和发现概率,结合采用减缩目标RCS的措施时,隐身性能的提高更为显著.有效辐射功率为1kW的自卫或随队干扰可以使飞行器的等概率探测范围由无主动干扰的几百公里半径减小到几十甚至十几公里半径,结合采用减缩目标RCS的措施时,其等概率探测范围几乎缩小为0.

Abstract: It was formulated that the calculation method of stealth performance of aircraft on condition of stand-off jamming and self-screening jamming. They were discussed the influence of various type of jamming and RCS on the stealth performance. The conclusions were made that the effective radiation power of 10kW stand-off jamming and 1kW self-screening jamming would notably reduce the exposed region with equal detection probability and the detection probability. The effect would better when combined with the RCS reduction technology.
