摘    要:针对间歇采样转发应用于宽带ISAR干扰问题,研究了间歇采样转发信号经解线频调ISAR二维成像处理后信号特性,通过推导干扰信号对应的二维输出形式,讨论了干扰图像变化情况并由此分析了间歇采样周期和占空比对干扰效果的影响。利用数字仿真验证了干扰输出形式及图像特征理论分析的正确性;将实测数据与间歇采样转发处理相结合,初步验证了间歇采样转发干扰能够形成二维ISAR假目标。

关 键 词:成像雷达  解线频调  ISAR干扰  转发干扰  间歇采样

Abstract:It is potentially useful to perform deception jamming by the use of intermittent sampling repeater jamming in ISAR, thus the characteristics of the repeated jamming signal after dechirping are investigated. Based on the two dimensional expression of the output, the features of the jamming in ISAR are discussed and the various jamming effects with different intermittent sampling intervals and duty ratios are also addressed. The analysis is demonstrated by the simulations. Additionally, the two\|dimensional false target images are also validated preliminarily associated with measured data.
Keywords:Imaging radar  Dechirping  ISAR jamming  Repeater jamming  Intermittent sampling
