The focused synthetic aperture imaging processing is the available method to improve the azimuthresolution, but the operational quantity is so large that it could not accomplish in real time.
合成孔径成像是提高图像方位向分辨率的有效方法,但算法运算量大,在机载条件下往往实时性得不到保证。

In an airborne SAR real time imager, the selection of azimuth pre filter ratio has a decisive effect on the final azimuth resolution.
在机载sar实时成像处理器中,方位预滤波比的选取对最终获得的方位分辨率有决定性的影响。
