摘    要:对于机动目标,目标相对于雷达的转动在一定条件下近似为匀加速转动,运动补偿后目标各散射点回波多普勒频移可近似为线性函数.该文研究了此时逆合成孔径雷达(ISAR)成像的方法,讨论了横向分辨率和旋转角度的关系,并证明了在一般情况下和匀速转动时的关系是一样的

关 键 词:匀加速旋转目标  ISAR成像  横向分辨率

Abstract:For a maneuvering target, the rotational movement between radar and the target may be approximated as the uniformly accelerate rotation, and the Doppler frequency shifts of scatterers may be approximated as linear functions after movement compensation. The method of ISAR imaging in this case is investigated, and the relationships between the cross range resolution and the rotational angle is discussed. It has been shown that the relationships described here are nearly the same as those in the case of the uniformly rotational object.
Keywords:uniformly accerlerative rotational target  ISAR imaging  cross  range resolution
