| 中文摘要: |
| 本文将窄带逆波束形成算法扩展到宽带，将扩展拖曳阵方法的被动合成孔径技术与宽带逆波束形成技术进行了有效的结合，形成了一种新型的基于逆波束形成的被动合成孔径技术。有效的提高了扩展拖曳阵技术的探测性能，改善了传统的ETAM技术在低信噪比下性能急剧下降的问题，与常规波束形成对比获得了更高的方位分辨率，同时对于多目标及弱目标检测能力也更为优异。 |
| 英文摘要: |
| In this paper, the narrowband inverse beamforming is extended to broadband. The passive synthetic aperture technology based on extended towed array method and broadband inverse beamforming method in frequency domain was combined together. It forms a new efficient synthetic array technology based on broadband inverse beamforming method. The technology improves the detection performance of extended towed array method effectively. The azimuth resolution of this method is higher than the conventional beamforming, and the detection ability of the multi-target and weak target is more excellent. |
