摘要

提出了一种FMCW雷达系统的快速DOA估计方法。为了实现快速的处理速度，该方法将MUSIC算法与牛顿法相结合。采用牛顿法中常用的单脉冲比相法来获得初始角。另外，定义了一个代价函数来求MUSIC谱的最大值。通过对研制的77GHz FMCW雷达实测数据的分析，测量结果表明，该方法的处理速度比传统MUSIC算法提高了54%。

Fast DOA Estimation Method based on MUSIC algorithm combined Newton Method for FMCW Radar

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.
