多普勒波束锐化成像技术(DBS)能为检测出的动目标定位提供参考,从而有效地实现精确打击。DBS技术在弹道导航、地形匹配等许多方面有着广泛的应用。首先简述了DBS成像方法的一般工作原理,经分析得出结论:DBS成像在SAR/GMTI模式下应用时,如果引入聚焦型的SAR处理方法,即通过去距离单元走动、去方位向调频斜率等方法可有效提高雷达成像质量。最后利用雷达实测数据进行处理,得出了较满意的高分辨DBS成像结果。 Doppler beam sharpening imaging (DBS) can provide a reference for the detection of moving target positioning, so as to effectively strike with precision. DBS technology has a wide range of applications in many areas such as ballistic navigation, terrain matching. First of all, the general working principle of DBS imaging method is briefly described. The conclusion is drawn from the analysis: when DBS imaging is applied in SAR / GMTI mode, if the focus-based SAR processing method is introduced, that is, Other methods can effectively improve the imaging quality of radar. At last, the data measured by radar are processed and the satisfactory results of high resolution DBS imaging are obtained.
