摘要
论文讨论了窄Stretch信号用于ISAR成象的可行性。详细地分析了窄Stretch信号所特有的平方相位项对成象及散射重心运动补偿法的影响,并提出了一种消除平方相位项影响的运动补偿方法。理论分析与计算机模拟都表明了这种方法是有效的。
The feasibility of the application of a short-stretch signal to ISAR imaging is discussed. The quadratic phase of the short-stretch signal and the effect of the quadratic phase on imaging and scatter-center motion compensation [1] are analyzed in detail. A mo- tion compensation scheme for eliminating the effect of the quadratic phase of the short-stretch signal is put forward. The theoretical analysis and computer simulation show that this scheme works.
