| 摘 要： | 针对脉冲多普勒雷达采用脉冲压缩技术,相参积累等相参技术,并采用相干旁瓣对消和旁瓣匿影抗干扰技术,因此具有很强的抗干扰能力。首先介绍了基于噪声卷积和间歇采样两种灵巧噪声干扰方法的基本原理,为了证明灵巧噪声干扰的有效性,采用低重频下PD雷达为干扰对象进行干扰仿真试验。为了能够提高干扰效果,提出了改进方法,并进行计算机仿真。仿真结果表明,灵巧噪声干扰能很好地干扰相参体制雷达。

| Abstract: | Pulse Doppler radar has strong anti-jamming ability by means of coherent technology such as pulse compression techniques and coherent integration technique,and anti-interference technology including coherent side-lobe cancellation and side-lobe blanking techniques.The paper firstly introduces the basic principles of two smart noise jamming methods based on the noise convolution jamming and interrupted-sampling repeater jamming(ISRJ).In order to verify the effectiveness of smart noise jamming,low pulse repetitive frequency PD radar is taken as the target of jamming in the jamming simulation test.To improve the jamming effects,an improved method is proposed and computer simulation is performed.The simulation results show that smart noise jamming can jam coherent radar well. |
