基于ICW-RCM的辐射源组合威胁评估

针对传统辐射源威胁评估方法难以直观地给出目标威胁程度以及在实时性、复杂性上的不足,在雷达图法(radar chart method, RCM)的基础上,提出基于改进组合赋权(improved combination weighting, ICW)-RCM的辐射源组合威胁评估算法。组合威胁评估将辐射源威胁等级粗排序和精细排序相结合,根据雷达指标计算雷达工作模式,对辐射源威胁等级进行粗排序,并降低威胁程度低的辐射源任务优先级;基于ICW-RCM,对相同雷达工作模式的辐射源精细化排序,并结合粗排序结果,得到最终的辐射源威胁评估结果。实验仿真与分析表明,该算法具有较好的正确性与有效性,与传统组合赋权雷达图法相比算法复杂度较低、实时性较高、结果更加形象直观。

Combined emitter threat assessment based on ICWM-RCM

Considering that the traditional emitter threat assessment methods are difficult to reflect the degree of target threaten intuitively and the deficiency of real-time and complexity, on the basis of the radar chart method (RCM), an algorithm of combined emitter threat assessment based on improved combination weighting (ICW)-RCM is proposed. Coarse sorting is integrated with fine sorting in combined emitter threat assessment. Firstly, sequence the emitter threat level roughly according to the radar operation mode, and reduce task priority of the low-threat emitter. Then, on the basis of ICW-RCM, sequence the emitters with the same radar operation mode. Finally, obtain the results of emitter threat assessment which combines coarse sorting and fine sorting. Simulation analyses show the correctness and effectiveness of this algorithm. Comparing with classical methods of emitter threat assessment based on CW-RCM, the proposed algorithm is visual in image and can work quickly with lower complexity.
