摘要

合成孔径雷达借助综合孔径原理来提高方位分辨率

而距离分辨率的提高则需借助于脉冲压缩技术.频率步进波形是通过发射载频步进变化的子脉冲串来合成大带宽信号

从而获得高距离分辨率.若将频率步进波形应用于合成孔径雷达

则可获得距离和方位的二维高分辨率.本文首先分析了径向速度对频率步进雷达一维距离像的影响

然后建立频率步进信号照射下的合成孔径雷达回波模型

提出频率步进波形设计原则

给出频率步进合成孔径雷达的成像步骤.

Abstract

SAR obtains high azimuth resolution through synthetic aperture integration and high range resolution via pulse compression.Stepped-frequency waveform achieves large bandwidth by sequentially changing carrier frequency over pulses.In order to obtain high resolution in two dimensions

we try to apply stepped-frequency waveform to SAR system.First

the effect of radial velocity on synthetic range profile is discussed

then the return of stepped-frequency SAR is presented.Furthermore

the waveform design is discussed

and the method of SAR imaging is given.
