| 摘 要： | 研究了对干扰前不同图像质量的合成孔径雷达(SAR)的干扰效果问题。从干扰前SAR图像质量指标积分旁瓣比(ISLR)入手,提出等效信干比的概念,建立积分旁瓣比与等效信干比的关系,分析等效信干比与发现概率、错误概率的关系,最后确定不同图像质量所对应的所需信干比。

| Abstract: | This paper studies the jamming effect of SAR with different pre-jamming image quality.The concept of(equivalent) signal-to-jamming ratio is proposed starting from pre-jamming integrated side-lobe ratio(ISLR).The relation between integral sidelobe ratio and equivalent signal-to-jamming ratio is established and the relation between equivalent signal-to-jamming ratio and probability of discovery and error probability is analyzed.Finally,the required signal-to-jamming ratio corresponding to different image quality is determined. |
