对影响雷达方位分辨率的因素进行了分析，提出用于目标回波图像模拟的雷达波束数字化模型和相应目标散射模型。
This paper analyzes the factors affecting radar bearing resolution, provides digital beam model and target scattering model to simulate target echoes image.
在合成孔径雷达（SAR） 中，雷达与目标之间相对运动的精确知识是相干处理回波形成高方位分辨率图像的基础。
The problems about the detection of moving objects and observation by the synthetic aperture radars(SAR) are described in this paper.
这样，利用多普勒频移现象“合成”一个更大的孔径，达到“增加天线长度”的效果，提高雷达图像的方位向分辨率。
So, a larger aperture can be composed, and we obtain a good purpose of increasing the length of the antenna, and we obtain a better Radar image on the orientation.
一般非综合孔径雷达的方位分辨率受天线波束宽度的限制。
Angular resolution of a real aperture radar is limited by the beam width of the radar antenna.
该方法首先对各距离分辨单元在方位向进行非相参积累，然后利用类似单个脉冲下扩展目标的广义似然比检测器来实现高分辨率雷达的检测。
First, each range resolving unit was accumulated non-inherently in azimuth, and then the detection of HRR target was done with the GLRT detector similar to that of the mono-pulse spread targets.
