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1550nm的激光对33.5m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18cm和1.576kHz。
A real-time data acquisition inverse synthetic aperture lidar imaging system is designed. The system uses a continuous m-sequence phase modulation scheme based on a 2 W, 1550 nm wavelength laser to image a rotating target 33.5m away. Distance - Doppler domain imaging results clearly reproduce the target features. In the imaging example, the distance resolution and the orthogonal distance resolution are 18 cm and 1.576 kHz, respectively.
