摘　　要：随着电子战中雷达网的"四抗"能力不断提升,干扰机的功率如何进行分配将成为战机突防的关键。针对此问题,提出了基于目标威胁评估的协同电子干扰的功率分配方法。建立了一种组网雷达的威胁评估模型,该模型通过规范化的基本方法,计算出雷达各属性对应的威胁评估值,得到雷达威胁评估值规范化矩阵。通过计算其与理想解的距离得到相对贴近度,进而计算出各成员综合威胁程度。根据其威胁程度的比重,在干扰功率有限的前提下,进行较为合理的分配。最后经过仿真验证,证明了该方法的可行性。结果表明:选取合适的组网雷达待评估属性,利用该方法可以得到干扰功率分配的初步规划,对该领域的后续研究具有一定的参考价值。With the growth of four countering capability of the radar network in electronic warfare,the allo- cation power of jammer becomes a key to the aircraft penetration. For this reason, a method of power allo- cation based on threat evaluation of collaborative electronic jamming is given. A kind of the radar network threat assessment model is established,and the basic methods of the model through standardization calcu- late the radar threat assessment value of each attribute corresponds to get radar threat assessment value standardization matrix. The paper obtains a relative degree through calculation of the distance and an ideal solution,and comprehensive threat level calculated for each member. A reasonable power distribution can be performed through the threat level proportion of the radar network on the premise of limited jamming power. Finally, the simulation shows that the method is feasible. The results show that in selecting ap- propriate radar network for evaluating parameters, interference power allocation can be achieved by using the method, and has a certain reference value for further research in this field.
