%X Tradition methods that simulate the micro-Doppler signal echoes of human motion for radars can only suit for simple motion model and the established human model has little similar with real human figure. Aim to this, this paper proposed a method based on the motion captured file. At first, it calculated the position transformation of articulations from the motion files. Subsequently, established a three dimension human model, which was composed by twelve ellipsoids, base on the positions of articulations, and simulated the RCS of human body based on the established model. The proposed method can calculate the echoes for arbitrary model of human motions; also, the established model is similar with human figure. Simulation results show the efficiency of the method.
