摘要
现役第四代主动雷达型空空导弹普遍采用被动跟踪干扰源技术应对噪声压制性干扰,为对其进行有效对抗,研究了一种新的灵巧噪声干扰信号——扫频锯齿波信号。干扰信号通过在原有雷达回波上附加一个窄带线性调频信号产生,用较小的功率在目标回波附近产生类似高斯噪声的特性。以最小干扰距离和脱靶量为评估指标进行建模分析,仿真结果表明,该灵巧噪声干扰能够有效干扰导引头,具有很高的功率利用率。
Homing-on-technology is widely used in active ARAAM to counter blanket jamming. A new kind of smart noise,sawtooth FM signal,put forward to treat with the HOJ mode of ARAAM. The jamming signal is generated by adding a narrowband LFM signal in original radar echo,which features that analogy to Gaussian using small power smart noise jamming analyzed and modeled with the reference standard of minimum jamming distance and miss distance. Simulation results show that this smart noise high efficiency can jam radar seeker effectively.
