To generate the excitation signal of radar synchronous motor which can obtain the azimuth and elevation of radar antenna, high-speed DSP was used to generate SPWM by the arithmetic of asymmetry rule sampling. The advantage, theory, and mathematic model of SPWM were deeply analyzed. Based on TMS320LF2407A, the process of obtaining SPWM was given. Finally, the test waves were analyzed. The result of experiment shows that it has advantages of high precision, real time, and simple structure to use DSP on the generation of SPWM.
