提出了一种新型的基于激光收发阵列的前视合成孔径激光雷达(SAL)成像系统。给出了系统的结构模型,分析了系统成像原理,详细推导了点目标的回波模型和适用于前视SAL的ECS算法,最后通过Matlab对6点目标的情况进行了成像仿真,对点目标峰值中心的64×64点切片和方位向、距离向包络进行了详细分析,结果表明该系统可以有效地对雷达前视场景进行成像。
A novel forward-looking synthetic aperture lidar (SAL) imaging system based on laser transceiver array is proposed. The structural model of the system is given, the principle of system imaging is analyzed, the echo model of point target and the ECS algorithm for forward-looking SAL are deduced in detail. Finally, the imaging simulation of 6-point target is carried out by Matlab, The peak center 64 × 64 slice and azimuth, the distance to the envelope were analyzed in detail, the results show that the system can effectively radar imaging scene.
