摘要
合成孔径激光雷达利用激光信号的大带宽和短波长,能够实现对目标的超高分辨成像,已经成为国内外研究的热点问题。分析了合成孔径激光雷达的成像原理,建立了相应的数值仿真模型,模型考虑了雷达的输出功率、作用距离等各种因素对雷达性能的影响,并对成像结果进行了仿真,客观地反映合成孔径成像激光雷达在不同条件下应该探测的结果,有助于实验系统的方案设计和性能改进。
Synthetic aperture lidar（SAL） can realize high resolution imaging with the laser signal which has large bandwidth and short wavelength,so it is becoming research hotspot.In this paper,the capability of SAL is analyzed,the imaging theory is discussed,the model is set up.The model is based on t he laser radar principles,and it concerns lidar transmit power,range equation,etc,and simulate the imaging program.The results can provide the design of SAL system.
