摘要
为提高汽车防撞雷达测角反应速度,结合ESPRIT和MUSIC算法的优点,提出一种多载频MIMO汽车雷达ESPRIT-MUSIC快速联合算法。方法通过采用MIMO雷达产生虚拟阵列来减小系统体积。首先利用ESPRIT算法粗估目标角度,然后通过MUSIC算法在粗估角度附近进行谱峰搜索,精确估计目标位置。仿真结果验证了所提方法的可行性和有效性。
By combining the advantages of ESPRIT and MUSIC algorithms,the ESPRIT and MUSIC combined algorithm for multi-carrier-frequency MIMO radar on car is proposed to improve the speed of angle measurement of vehicle collision avoidance radar.The system volume is reduced by using MIMO radar to generate virtual array.The target angle is estimated roughly with ESPRIT algorithm firstly.And then the accurate angle is obtained by using MUSIC algorithm in the vicinity of the coarse estimation angle.The feasibility and effectiveness of the proposed method are verified by the simulation results.
