【摘要】 成像雷达一般可分为合成孔径雷达(SAR)和逆合成孔径雷达(ISAR)。研究目标的RCS特性当前普遍应用ISAR成像技术,而这些目标的成像能力都依赖于目标的回波信号。在ISAR三维成像理论的基础上,模拟离散点目标的回波信号,为三维成像软件提供三维空间的模拟数据,用来验证成像软件的正确性。基于已有的一维和二维成像软件对模拟数据进行了分析。从三维数据中提取出一维和二维数据,成像结果证明了模拟数据在一维和二维的有效性,从而保证了模拟数据三维成像可靠性。更多还原

【Abstract】 Imaging radar can be commonly classified into two categories,synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR).The usual technology to research RCS characters of target is based on ISAR imaging technology.The imaging capacity of target is depending on the echo signal of the target.This paper proposes a policy to simulate the echo signal of discrete targets based on ISAR 3-D imaging theory.It provides 3-D data simulation for 3-D imaging software in order to verify the validity of the software.Besides,The data is analyzed based on 1-D and 2-D imaging software.The result shows that the data is validity in 1-D and 2-D imaging,and thereby,it is can be validated that the data is reliability in 3-D imaging.更多还原
