摘要

结合角度脉冲压缩的概念和SAR的单一模型，提出了一种基于波束调制的角度超分辨方法。基于方位角方向波束扫描的线性调频，推导出波束扫描角度与频率映射关系的解析表达式。然后通过距离-方位角控制分别在距离和方位角方向上对一个脉冲体积内未解析目标进行识别。仿真结果表明，该规则提高了多目标分辨率。

An Angular Super-Resolution Method Based on Beam Modulation

Combined with the concept of angle pulse compression and the single model of SAR, a new method for angular super-resolution based on beam modulation is proposed. Based on the linear frequency modulate for beam scanning in azimuth direction, the analytic expression of the mapping relationship between angle and frequency is deduced. Then the unresolved targets in one pulse volume can be identified in range and azimuth directions by the range-azimuth control separately. The simulation results indicate that the proposed rule improve the multi-target resolution.
