摘　　要：针对用于调制分类过程中雷达信号脉内特征参数评估问题,提出了一种多指标联合评估方法。该方法使用复杂性、可分离性和稳定性3个指标对特征参数的调制分类性能进行联合评估,克服了传统评估手段仅使用单一指标难以进行全面科学评估的缺陷,并可以根据应用需求获取相应的最合理的综合评分值。理论分析和计算机仿真结果表明,该方法可以有效评估特征的调制分类性能,具有较强的工程应用价值。A multiple-factor-method for benchmarking the performance of radar signal intra-pulse features is proposed. Three factors, i . e. complexity,separability and stability,are employed,in contrast with the conventional technique which cannot fully assess the performance because only single factor is used. More- over,a synthesized metric is given by the method under various conditions. Both theoretical analysis and simulations indicate that the proposed method can assess the performance of introduced features effectively. The research shows the applicability of the method in practical projects.
