Pulsed laser ranging has been widely used in the fields of space rendezvous and docking,satellite navigation,radar,communication,topography and so on,which has many merits such as far distance measurement,high precision of ranging and good directivity.In this thesis,the cause of the ranging error was analyzed and the model of the ranging error was established.The pulsed laser drive circuit was designed to reduce the pulse width of the pulsed laser signal and increase the laser drive current,The output pulse...
