Abstract
The means of coherent Doppler has obvious advantages to obtain the target range change. Based on laser Doppler effect, designed a set of imaging Doppler lidar experimental system. Introduction all phase measurement phase treatment consideration to do time-frequency analysis for heterodyne signal, restraining spectral leakage and reducing the impact of noise on the measurement results, a high measurement accuracy signal frequency curve will be acquired. The process simulation in the simulink interactive simulation integration environment which comes with MATLAB software, to prove it can achieve higher resolution, high precision imaging for scan space. The experimental results show that the system was able to restore the surface of target feature preferably. It plays a promoting role in high-resolution and high-sensitivity imaging of the target for lidar.
