An experiment set-up is constructed to measure the transverse velocity of a moving target by using dual beam mode of CW CO2 laser in the laboratory.The experiment is conducted in the laboratory using dual-beam mode and clear Doppler frequency signals are recorded,and signal data filtering is performed leading to an enhanced SNR.The calculated velocity of the moving target is compared with the actual velocity.The result shows that the measured velocity corresponds with the actual velocity very well.
