摘　　要：针对电磁环境具有动态演化的特点,提出了一种改进的复杂度定量评估方法。在评估指标集上,选取信息量变化率作为电磁环境演化特征的衡量参数。评估样本的获取结合搜索数据的时频分布,以聚类和Hough变换的方法快速估计信息量变化率。最后采用自适应神经模糊推理系统模型实现了电磁环境复杂度的定量评估。实验验证了所提方法的有效性。Electromagnetic environment is dynamic and evolutional.Aimed at this characteristic an improved method of the quantificational evaluation on the complexity is presented.Among the index set of evaluation,the rate of variable information is adopted as the scale parameter to reflect the evolutional characteristic of electromagnetic environment.Using the technique of cluster and Hough transformation,the rate of variable information is quickly Abstracted from the time-frequency distribution of scanner data and integrated into the acquisition of evaluation sample.Finally,the adaptive-network based fuzzy inference system is introduced to implement the quantificational evaluation on the complexity of electromagnetic environment.The experimentation demonstrates the validity of the proposed method.
