| 摘 要： | 提出一种实波束扫描雷达前视成像回波建模方法。使用实波束扫描实现雷达平台正前视区域二维高分辨成像。根据雷达波束掠过成像扇区的时间先后关系，将成像扇区方位向回波数据表征为天线主瓣波束采样序列与目标反射率分布函数沿成像扇区方位向采样序列之间卷积的形式。最后，通过仿真数据验证了本建模方法的有效性。

| Abstract: | A method is presented for echo modeling of real beam scanning radar. Aiming at application requirement of two-dimensional high resolution imaging in the forward area of radar platform, a technical approach is put forward by using real beam scanning radar platform. The basic idea is to convert the azimuth echo data to the convolution form of main lobe antenna beam sampling sequence and the target reflectivity sampling sequence along the imaging sector orientation, according to radar beam scanning time for imaging sector. Finally, the effectiveness of the modeling method is verified by simulation results. |
