为满足部队抗干扰训练的需要,分析了EA-18G电子战飞机的干扰能力,给出了一种干扰环境等效构建方法.利用干扰设备模拟器,考虑干扰信号进入方向和干扰机运动模型,根据功率等效原则,对电子战飞机干扰环境进行模拟构建;然后根据干扰距离、方式与模拟器相对雷达距离变化之间的定量关系,给出了干扰机、雷达、模拟设备之间的模拟变化曲线;最后结合实验实现了对多批目标和干扰环境的复杂模拟.仿真与实验结果表明,该方法能够高效地构建电子战飞机对雷达的干扰环境,为部队抗干扰训练提供有力支撑.

In order to meet the needs of anti-jamming training,the paper analyzes the jamming capability of EA-18G electronic warfare(EW)aircraft,and presents an equivalent construction method of jamming environment.Based on the principle of power equivalence,the jamming environment of EW aircraft is simulated by using the jamming equipment simulator,with the direction of jamming signal and the movement model of the jammer considered.Then,according to the quantitative relationship between the jamming distance,mode and the change of simulator distance from radar,the simulation curve of jammer-radar-simulator is given.Finally,the complex simulation of multi-batch targets and interference environment is realized with experiments.The simulation and experimental results show that the proposed method can effectively construct the jamming environment that EW aircraft form against radar,and provide strong support for anti-jamming training of troops.
