摘　　要：步进跳频信号可实现距离维高分辨 ,文中给出了点目标合成宽带处理结果 ,并从频域采样的角度对步进跳频信号的跳频间隔进行了深入的分析。对步进跳频信号 ,导出了跳频间隔选取受到发射脉冲宽度严格限制的约束条件。对应用于小目标的步进跳频信号 。The principle to make use of using stepped-frequency to achieve high range resolution is described and the analysis of synthetic wide-band is given. Using frequency-domain sampling theory, the stepped-frequency interval is analyzed in detail. For stepped-frequency signal, the limiting condition of stepped-frequency interval by pulse width is obtained. For small target, the limiting condition of stepped-frequency interval by target length is derived.
