摘　　要：针对外太空干扰机产生的与雷达真实目标回波高度逼近的有源假目标干扰,在雷达数据处理环节可通过动力学守恒定律对此类假目标进行过滤,从而导致常规的转发式假目标无效。基于精细运动学调制原理,从理论上推导假目标欺骗参数与动力学参数(动量矩)之间的关联关系,将其化简为一个一元二次方程,并导出假目标欺骗参数的解析表达式。通过仿真实验比较传统假目标和精细调制假目标的对抗性能。研究结果表明,新方法产生的假目标航迹运动学特性几乎与实体目标相同,可以达到以假乱真的目的。For the active high fidelity decoy jamming generated by exo- atmospheric jammer,the decoys at the radar data processing level can be discriminated based on dynamics conversation law. That makes the conventional decoys invalidate to some extent. The correlative relationship among the active decoy parameters and the kinematics parameters is derived theoretically based on the moderate kinematics modulation principle. The relationship is simplified to a quadratic equation,and analytic expression is also derived. The countermeasure performances of the conventional false targets and the moderate modulated false targets are compared by computer simulation. The study illustrates that the kinematic characteristics of the active high fidelity decoys generated by the proposed method are the same as those of the true targets,achieving the purpose of mixing the false with the genuine.
