| 针对基于数字射频存储（DRFM）的雷达高度欺骗干扰方法存在假目标逼真度低、易被识别和易被滤除的问题，为提高假目标干扰效果，根据雷达顺序波瓣法测仰角和DRFM干扰机的工作原理，提出功率等比转发与比例延时相结合的假目标高度控制算法，阐述了无人机载DRFM干扰机实施干扰的工作流程。经仿真计算，对比了高度控制算法、非均匀重复转发和功率颠倒转发所产生的假目标在航迹、高度和速率方面的差异，证明了高度控制算法产生的假目标运动状态更接近于真实目标，从而验证了该方法的有效性。 |

| Abstract: |
| There are some problems in the method of height deception jamming based on the digital radio frequency memory（DRFM),such as the low fidelity of the false targets and the easy recognition and filtering of the radar. According to the working principle of elevation measurement of sequential lobe and DRFM,a method of height control algorithm composed of power proportional forwarding and proportional delay is presented to improve the jamming effect of false targets. The working process of the unmanned airborne DRFM is described,and the differences between the height control algorithm,nonuniform periodic repeater jamming and power inversion forwarding in the track,altitude and speed are compared through software simulation. It is proved that the motion state of the false targets produced by height control algorithm is closer to the real targets. So the method is effective. |
