Extending MUSIC algorithm by using virtual array technique
In array signal processing, one is often interested in simultaneously estimating the directions and frequencies of uncorrelated narrow-band radiating sources having different center frequencies. We present a new high-resolution signal estimation algorithm which can estimate the spatial direction /sp...

| description | In array signal processing, one is often interested in simultaneously estimating the directions and frequencies of uncorrelated narrow-band radiating sources having different center frequencies. We present a new high-resolution signal estimation algorithm which can estimate the spatial direction /spl theta//sub i/ and temporal frequency f/sub i/ of each source by using the virtual time-and-space array technique with MUSIC algorithm. The virtual linear array consists of one spatial subarray and one virtual temporal subarray and the parameter pair (/spl theta//sub i/, f/sub i/) of each source can be easily obtained and automatically coupled. The proposed approach is simple and direct. Simulation results are presented to demonstrate the performance of the proposed technique. |
