【摘要】 在新一代军事战争中,3D LADAR发挥着越来越重要的作用。首先,论述了基于调频连续波原理的三维成像激光雷达系统以及它的基本工作原理。其次,研究了三维成像激光雷达接收端的信号处理仿真,给出了频带宽度为300 Hz的LFM信号及幅频特性仿真图,实现了多距离目标回波混频信号及距离信息提取。最后,指出该3D LADAR系统是未来军事领域中发展的重要方向。更多还原

【Abstract】 The 3D LADAR is playing a very important role in the modern wars.First,it introduces the application of 3D LADAR system and expounds the basic working principle of 3D LADAR and the 3D LADAR system which based on the FMCW principle.Next,it deeply researches on the receiver signal processing simulation of the 3D LADAR,gives 300 Hz frequency band width of the LFM signal and amplitude-frequency characteristic simulation finger and realizes multi-mixer from the target echo signal and extracts the distance information.In the last,it points out that the 3D LADAR is the important developing direction in the war in future.更多还原
