摘　　要：双基地雷达由于其收、发站分置具有较好的抗干扰性能。从双基地雷达方程和压制性干扰带来的热噪声的变化出发,推导出了对双基地雷达进行分布式压制性干扰的数学模型。分析了分布式干扰下各种干扰情况对双基地雷达探测能力的影响,并与自卫式干扰和远距离支援式干扰进行了比较。仿真结果表明,对双基地雷达实施分布式压制性干扰可以达到较好效果。The bistatic radar that transmitting and receiving stations are separated has enhanced ECCM ability. Combined with bistatic radar equation and heat noise transformation from blanket jamming, the mathematical models of distributed blanket jamming to bistatic radar are deduced. The effect of distributed jamming on detectability of bistatic radar is analyzed under different jamming conditions, and the results are compared with the effect of stand off jamming and stand forward jamming. The simulation result shows that the distributed jamming is effective.
