摘要
作为典型的高分辨率雷达,逆合成孔径雷达(ISAR)能够对观测目标进行全天候、全天时、远距离的成像。采用非合作目标ISAR成像模型及步进调频信号的ISAR成像技术,阐述了平动补偿、最优成像时间段的选取、横向距离高分辨率,进行了非合作目标的二维ISAR成像设计。
As the typical high-resolution radar ,the inverse synthetic aperture radar （ISAR） can per-form all-weather ,all-time and long-distance imaging .This paper adopts ISAR imaging model of non-cooperative target and ISAR imaging technique of step frequency modulation signal ,expatiates the translational motion compensation ,selection of optimal imaging time segment ,lateral distance high-resolution ,performs the two-dimensional ISAR imaging design of non-cooperative target .
