升采样，用于分析ISAR/SAR成像算法成像质量，分析点目标距离向/方位向剖面切片，观察主瓣与旁瓣，也可以用于定性分析不同算法对同一目标点成像质量的好坏。也可用于分析峰值旁瓣比与积分旁瓣比等。-Liter sample for analysis ISAR/SAR imaging algorithm image quality, the analysis points to the target distance/azimuth cross-sectional slices, observe the main lobe and side lobes to be good or bad for the qualitative analysis of different algorithms on the same target image quality. It can also be used to analyze the ratio of peak sidelobe sidelobe integral ratio.
