摘　　要：为更好地评估对合成孔径雷达(SAR)的干扰效果,提出了一种基于层次分析法(AHP)和目标检测识别性能的评估方法。首先,根据战术背景对成像区域进行划分,利用AHP计算各区域的评估权重;而后,针对目标检测识别性能衰减情况设计评估指标,并根据干扰样式计算区域评估结果;最后,结合区域评估权重加权计算综合评估结果。仿真实验结果表明,该评估方法能与战术背景、作战需求紧密结合,较好地适用于近实时和非合作的评估场景。In order to evaluate the jamming effectiveness of synthetic aperture radar(SAR)better,an evaluation method based on analytic hierarchy process(AHP)and performance of target detection and recognition is proposed.Firstly,the imaging region is divided according to the tactical background,and the evaluation weight of each region is calculated by AHP.Then,the evaluation index is designed according to the attenuation of target detection and recognition performance,and the regional evaluation result is calculated according to the jamming form.Finally,the comprehensive evaluation results are calculated by combining the regional evaluation weights.Simulation results show that this evaluation method can be closely combined with tactical background and battlefield requirements,and is suitable for near-real-time and non-cooperative evaluation scenarios.
