为衡量激光主动成像系统的性能,根据主动成像系统的成像过程,通过分析目标与背景的辐射特性、大气的后向散射特性,距离选通特性以及激光发射器和接收器的性能,建立了激光主动成像系统的信噪比模型。并利用工作波长为0.532μm的固体激光器,ICCD相机,以及基于CPLD技术设计的距离选通同步控制板,开展了距离选通激光主动成像实验,通过实验结果分析,验证信噪比模型的正确性。
To judge performance of laser active imaging system
based on system imaging process
the signal-noise ratio model of laser active imaging system was built by analysing target and background reflection character
atmosphere backscattering character
range gating character
the performance of laser and receiver
By using of solid laser of wavelength 0.532μm
ICCDcamera
sync control range gating plate based on CPLD technology
the experiment was done. finally the signal-noise ratio mode was verified.
