Technology of the rendezvous lidar measuring the object’s position

In order to measure the object's position and velocity,the method of counting pulse with analog interpolation is used to measure the distance,and the method of differential coefficient of the fitting curve based on least-square curve fitting that takes the exponential function is used to measure velocity,and the method of orientating facula with quadrant detector is selected to measure the orientation angles in the pulsed lidar measuring system.Computer simulation is performed with the MATLAB/SIMULINK.As a result,the distance precision is less than 0.01m,the velocity error is smaller than 0.02m/s.It can be concluded that the information measuring technology of pulse lidar is reliable.
