摘要

同步轨道星-空双站SAR 构型下(卫星作为发射端、浮空器作为接收端)，为了应用空时自适应处理(Space Time Adaptive Processing, STAP)方法更好地抑制杂波，进行地面慢速运动目标检测，有必要分析杂波特性。该文从地面运动目标检测角度出发，建立了同步轨道星-空双站SAR 杂波特性的理论模型，分析了杂波的角度-多普勒轨迹的距离依赖性特点，仿真实验证明了模型建立和理论分析的正确性。该文的理论模型和分析结论揭示了同步轨道星-空双SAR 这一新模式下的杂波特性，为该模式下地面运动目标检测方法的选择和研究奠定了理论基础。

期刊介绍： Journal of Radars was founded in 2012 by the Institute of Space and Astronautical Information Innovation of the Chinese Academy of Sciences (formerly the Institute of Electronics) and the China Radar Industry Association (CRIA), which is located in the high-end academic journal and academic exchange platform in the field of radar, and is committed to promoting and leading the scientific and technological development in the field of radar. The journal can publish Chinese papers and English papers, and is now a bimonthly journal. Journal of Radars focuses on theory, originality and foresight, and its scope of coverage mainly includes: radar theory and system, radar signal and data processing technology, radar imaging technology, radar identification and application technology. Journal of Radars has been included in domestic core journals and foreign Scopus, Ei and other databases, and was selected as ‘China's high-quality science and technology journals’, and ranked the first in the category of electronic technology and communication technology in the ‘Chinese Core Journals List (2023 Edition)’.
