摘　　要：针对强海杂波环境下,在时域上难以实现弱小目标的高分辨问题,提出频域仿形技术实现频域高分辨,获得目标的一维高分辨像。首先研究了频域仿形的条件,重点分析了雷达导引头仿形能力与弹目相对距离、弹目相对速度、迎头角及航向角的关系,并给出仿真结果。然后分析了加速度对频谱展宽的影响,提出了加速度通道补偿算法。最后给出了补偿精度要求。It is difficult to realize the high range resolution for the target in powerful ocean clutter, so the frequency profile modeling technology is proposed, which can get the high resolution information of the target in frequency domain. The precondirion of the frequency profile modeling is first analyzed and the factors impacting on the profile modeling ability are given with the simulation results. Then the acceleration impaetion on the frequency spectrum is given and the acceleration channel compensational algorithm is proposed. Finally, the acceleration compensational precision is given.
