摘 要:对鸟类目标进行高分辨成像是确保飞行安全的重要举措。针对现有雷达分辨率过低问题,提出了利用逆合成孔径激光雷达进行鸟类目标高分辨成像探测的构想。给出了逆合成孔径激光雷达实现鸟类成像的原理框图,以此为基础,建立了鸟类目标成像模型。仿真结果表明:本文模型可以获得鸟类目标高分辨像。
High-resolution imaging avian is quite significant for aviation security. Aimed at the lower resolution of the existed radar,an idea about avian can be detected and imaged by using Inverse Synthetic Aperture Imaging LIDAR( ISAIL) is proposed in this paper. On the basis of the principle sketch of the avian ISAIL system is given,the avian imaging model by using ISAIL is introduced. Simulation results suggest that the high resolution image of avian can be obtained by the proposed model.
