Study on Micro-motion Feature Extraction and Imaging of Target with Rotating Parts in Bistatic ISAR

  • 摘要: 由于空间的高度复杂性,双基地雷达系统中目标微动产生的微多普勒信息与单基地体制雷达有较大区别。该文以含旋转结构部件目标为例,推导了双基地ISAR系统中目标微动产生的微多普勒效应,并详细分析了其在距离-慢时间2维谱图域内的表现形式及特点。针对双基地雷达收、发分置的特殊空间结构的影响,修正了基于扩展Hough变换的目标微动信息谱图域提取方法,并通过仿真验证了修正方法在双基体制ISAR成像系统中的有效性。
