摘要
ISAR三维成像是ISAR新的研究热点技术。利用单天线ISAR系统,研究基于ISAR图像序列的三维成像方法。详细推导了ISAR图像序列三维成像原理,分析了三维成像的条件,介绍了三维重构的正交分解方法。最后用仿真数据验证了本文方法的有效性。
The target three-dimensional reconstructional method based on mono-static inverse synthetic aperture radar（ISAR） is proposed in this paper.The principle of three-dimensional reconstruction is deduced at first.Then,the three-dimensional reconstruction condition is analyzed.Furthermore,the orthogonal factorization method to reconstruct the three-dimensional target is given.Finally,the effectiveness of the proposed algorithm is verified by the simulated data.
