After azimuth compression, the sub-apertures are arrayed and synthesized to offer a full-aperture resolution image.

方位向压缩后，将各子孔径数据按时间先后排序拼接、运算，合成出全孔径分辨率图像。

And an optimum method of producing the azimuth reference function based on polynomial model is brought out, which has improved the azimuth compression effect successfully.

在对模拟得到的原始数据进行成像压缩过程中，本文提出了一种由实际距离拟合生成方位向参考函数的方法，成功的提高方位向压缩效果。
