近程宽带高分辨成像雷达技术研究

Study on Near-field Wideband High Resolution Imaging Radar Technology

宽带高分辨成像技术是雷达技术研究的重要内容。针对近程高分辨成像的应用背景,基于全息成像原理,采用多输入多输出正交合成虚拟全空间阵面的方法,通过单通道分时扫描等效合成有效阵面的途径,搭建近距离成像的原理实验系统,开展了实验验证,获得阶段性的原理系统成像结果,为后续研究奠定了基础。

Wideband high resolution imaging is important part in radar technology. Aiming at me near- field high resolution imaging application and using single channel time-sharing scanning equating synthe- size effective aperture, we apply sense spatial tactic imaging method, construct near range imaging experiment system, and research on experiment verification. From this, we achieve staged imaging experiment result, which establish groundwork for future study.
