- Abstract
- This paper proposes a fast DOA estimation method for FMCW radar systems. In order to achieve the fast processing speed, the proposed method utilizes the MUSIC algorithm combined the Newton method. It also utilizes the phase-comparison monopulse method to obtain the initial angle which is used in Newton method. In addition, a cost function is defined to find the maximum value of the MUSIC spectrum. By the analysis of the measured data using our developed 77GHz FMCW radar, measurements show that the processing speed of the proposed method is improved by 54 percent than that of the conventional MUSIC algorithm.
