摘要
分析了线性调频步进雷达信号(LMFS)的形式及成像的特点,利用对雷达发射信号的设计,提出了此类信号切实可行的运动补偿方案;提出了两种形成延展目标ISAR像的拼接方法;最后通过实测数据验证所提运动补偿方法的有效性并通过仿真验证了所提ISAR像拼接方法的正确性。
The features of the linearly modulated frequency stepped radar signal (LMFS) and imaging based on it are analyzed. A feasible scheme of target motion compensation is proposed by using designation of radar transmitting signal; ISAR image is achieved by two methods of ISAR image combination for LMFS. The effectiveness of the scheme of target motion compensation is shown by the theoretical analysis and processing of the practical data, and the effectiveness of these methods of ISAR image combination are shown by the theoretical analysis and computer simulation.
