摘要:

针对合成孔径雷达(synthetic aperture radar,SAR)有源干扰图像数据稀缺、抗干扰目标检测算法难以验证等问题,建立了SAR典型有源干扰多样式统一仿真数学模型。该模型利用回波模拟、干扰仿真和成像处理,在实验室环境下实现了低成本、大规模、快速地生成SAR干扰图像数据,能够仿真多种干扰情况,可以在重要目标附近精准地生成干扰。同时,利用该模型构建了高分辨率SAR图像干扰数据集(high resolution SAR images dataset-jamming,HRSID-J),提出一种干扰效果综合评估方法,并利用HRSID-J进行了评估验证。结果表明,所提方法充分考虑了压制和欺骗效果,能准确反映干扰影响。

Abstract:

To address the problems of scarcity of active jamming synthetic aperture radar (SAR) image data and difficulty in validating anti-jamming target detection algorithms, a typical SAR active jamming multi style unified simulation mathematical model is established. This model enables low-cost, large-scale, and rapid generation of SAR jamming image data in a laboratory environment through echo simulation, jamming simulation, and imaging processing. It can simulate various jamming scenarios and accurately generate jamming near critical targets. Simultaneously, the high resolution SAR images dataset-jamming (HRSID-J) is constructed using this model. A comprehensive evaluation method for jamming effects is proposed, and is validated using HRSID-J. Result indicates that the proposed method fully considering the effects of suppresses and deceives, accurately reflects the jamming impact.

Key words: synthetic aperture radar (SAR), active jamming, jamming simulation, jamming effect evaluation
