摘　　要：从双基地雷达方程和实施压制性噪声干扰前后所带来的热噪声的变化出发,给出了双基地雷达探测区和干扰暴露区的计算模型,分析计算了在自卫式干扰和远距离支援干扰条件下的双基地雷达抗有源压制性干扰性能,并与单基地雷达情况进行了比较,说明收发分置的双基地体制雷达具有较强的抗干扰能力。给出了仿真算例,结果验证了这种观点。Combined with radar equation and heat noise transformation from blanket jamming for bistatic radar, the calculation models about detection zone and exposure zone for bistatic radar are presented, and the performance of the bistatic radar in resisting the active blanket jamming is investigated under self-screening jamming and standoff jamming situations. Then comparing the situation of bistatic radar with that of the single static radar comes into conclusion that the transmit/receive separated bistatic radar has preferable antijamming ability. This viewpoint is validated by simulation result.
