摘　　要：针对传统拖距及拖速假目标干扰无法对抗雷达多目标跟踪模式的问题,将噪声遮盖压制干扰和假目标欺骗组合使用,提出了瞄频噪声遮盖与假目标欺骗干扰、灵巧噪声遮盖与假目标欺骗干扰、切片噪声与切片假目标欺骗干扰三种双模干扰技术。给出了三种双模干扰产生的机理,推导了三种双模干扰技术所需压制噪声带宽以及假目标拖距拖速参数,对比分析了三种干扰技术的优缺点。在雷达多目标跟踪模型下,通过数字仿真计算对三种双模干扰技术的距离、速度二维干扰性能进行了分析。仿真结论表明,三种双模干扰技术都可以对抗雷达多目标跟踪,其中灵巧噪声遮盖与假目标欺骗干扰干信比最高,切片噪声与假目标干扰延迟最小。通过公式推导和仿真结果为后续工程应用提供了理论依据。Aiming at the problem that the traditional range deception and speed deception can not counter the radar multi-target tracking mode,the combination of noise barrage jamming and deceptive false targets jamming is used.Three dual-mode jamming techniques are proposed:frequency-spot noise barrage and deceptive false targets jamming,smart noise barrage and deceptive false targets jamming,slicing noise and slicing deceptive false targets jamming.The mechanism of three dual-mode jamming techniques is given.The required bandwidth of noise suppression and the parameters of range deception and speed deception are deduced.The advantages and disadvantages of three dual-mode jamming techniques are compared and analyzed.Under the radar multi-target tracking model,the two-dimension range and speed performances of the three dual-mode jamming techniques are analyzed through digital simulation.The simulation results show that all the three dual-mode jamming technique can counter the radar multi-target tracking mode.In the three techniques,the smart noise barrage and deceptive false targets jamming has the highest signal to noise ratio while the slicing noise and slicing deceptive false targets jamming has the lowest jamming delay.The theoretical foundation to the following application in engineering is provided by formulas and simulations.
