摘要
设计了一个实时数据采集的逆合成孔径激光雷达成像系统。该系统使用基于连续m序列相位调制方案,采用功率为2 W、波长为1550 nm的激光对33.5 m外的转动目标进行成像。距离-多普勒域成像结果清晰地再现了目标特征。成像示例中,距离向分辨率和正交距离向分辨率分别为18 cm和1.576 kHz。
Abstract
A real-time data acquisition inverse synthetic aperture ladar system is designed. The continuous m-sequence phase modulation method is employed to image a rotating target at a distance of 33.5 m by a 1550 nm laser with the average power of 2 W. The range-Doppler domain imaging result reveals the characteristic of the target, distinctly. In the imaging demonstration, the range resolution and the cross-range resolution are 18 cm and 1.576 kHz, respectively.
