| 摘 要： | 为提高合成孔径激光雷达(SAL)的分辨率,从激光脉冲调制与脉冲重复频率(PRF)的矛盾入手,提出了一种沿方位向放置多个望远镜接收的系统设计方法,利用空间自南度解决由于较低PRF带来的方位模糊问题.分析了SAL系统由于平台连续运动的影响(表现为多普勒频移项),提出了多普勒平移补偿方法.通过仿真实验验证了本文所提系统设计的...

| Abstract: | Synthetic aperture lidar(SAL) is a new active imaging system,which can offer a finer azimuth resolution than conventional SAR systems.The concept of equivalent phase center was described.After analysis of the conflict between the modulation of laser signal and pulse repetition frequency(PRF) of the lidar system,which leads to the ambiguity of the Doppler domain in the azimuth direction,a proper system was given,which uses a series of telescopes placed in the azimuth direction.This system makes u... |
