摘　　要：雷达欺骗式干扰性能评估是电子对抗领域的一个重要课题。现有评估技术都是基于某单一特征,评估结果比较片面。针对这一不足,提出一种基于目标识别与模糊综合评判的SAR欺骗式干扰性能评估方法,综合考虑目标识别系统可能应用的识别特征,利用模糊综合评判的方法对虚假目标图像的逼真度进行综合评判,然后考虑系统处理时间对干扰性能的影响,对综合评判结果进行修正,该方法具有一定的理论和现实意义。Performance evaluation of radar deception jamming is important in the field of electronic countermeasures.The existed evaluation methods are mostly based on certain single recognition feature,and corresponding evaluation results are unilateral.A new evaluation method for SAR deception jamming based on target recognition and fuzzy synthetical evaluation is proposed for the disadvantages.The similarity of false target image is evaluated by using fuzzy synthetical evaluation method in light of the features used by automatic target recognition system,and the synthetical evaluation result is modified by thinking over the influence of processing time to jamming performance.
