In recent years,the high-speed development of optical devices and digital processing technology has provided the basis for the miniaturization of the coherent continuous wave laser radar detection system. The radar has the advantages of high accuracy,high resolution of distance,small size,light weight and easy loading. In this paper,the principle of all fiber coherent continuous wave laser radar ranging and speed measurement is introduced firstly. Secondly,a set of parameters are designed according to performance indicators of all fiber coherent continuous wave laser radar. Then several simulations are done. At last,actual measurements using the radar are made. The simulation data and experimental data show that the high range resolution( 1 m),the large velocity range(-100 ~ 100 m / s) and the high accuracy rate( 0. 5%) can be achieved by using this parameter. The design target has been achieved.
