摘要
针对目前多信号环境中信号的测频测向问题,利用非均匀时延,解开频率和信号到达角之间存在的耦合,在此基础上实现了解耦合的二维MUSIC算法。可同时测量信号频率和到达角,计算量小,并保持了MUSIC算法测量精度高的特点。仿真结果证明了该方法的有效性。
A new kind of decoupling MUSIC algorithm for frequency and bearing measurement is proposed, which utilizes an uneven delay structure to untie the couple between the frequency and the DOA(direction-of-arrival). This algorithm can measure the parameters pair of each signal with small computation burden, while the accuracy is high. The result of the simulation illuminates the effectiveness of the new algorithm.
