| 步进频率综合宽带技术是一种易于雷达工程实现的距离高分辨技术，但步进频率工作体制雷达对目标的运动十分敏感，因而步进频率综合宽带处理时需进行速度补偿处理。由于单目标成像处理不适用于速度不同的多目标情形，研究了多目标成像处理方法。多目标成像处理方法将脉冲压缩后多个目标的数据进行分割，对每个目标的数据段进行包络再对齐、速度补偿、综合成像、距离像拼接处理，最终得到包含多目标的完整距离像。仿真结果表明该方法有效、可行。 |

| Abstract: |
| Stepped frequency synthesis processing technology is a method easily realized in radar to obtain high-resolution range profile. However, the stepped frequency radar is sensitive to the targets motions, thus velocity compensation is needed in stepped frequency synthesis processing. Because the ordinary imaging method for single target is not suitable for multiple targets with different velocities, the imaging method for multiple targets is discussed in this paper. The multi-target image processing method divides the pulse compression data into several segments. And then range realignment, velocity compensation, synthesis imaging, and range profile splice are applied to each data segment to obtain the complete range profile containing multiple targets. The simulation results validate the effectiveness of this algorithm. |
