摘　　要：传统的激光雷达技术,多采用激光器的经典态作为发射端。随着量子技术发展,具有量子特性的非经典光源应用愈加广泛。这里在激光雷达系统的光源选择方面,对比了基于压缩态以及NOON态这两种典型的量子光源的系统噪声影响。结果发现,应用这些光源对雷达的噪声特性不会产生很好的改善,对雷达性能影响不大。For the traditional laser radar,laser pulses in classical states are used as the transmitter source.With the development of quantum technology,light sources with non--classical states are widely applied.Especially for the laser radar system,the fluctuations of the quantum noise in the system are analyzed when squeezed--state source and NOON--state source are used separately.Calculations shows the noise feature with little effect,which shows that applying quantum sources cannot benefit the laser radar system too much.

关 键 词：激光雷达 量子光源 量子噪声
