Abstract :
A linear time-frequency multiple signal classification (LTF-MUSIC) algorithm is proposed for separation and direction finding of nonstationary sources. The algorithm is based on the new array snapshots formed by sampling the time-frequency presentations (TFR) of the receive signals along the signal ridges. Numerical simulation validates the good performance of the proposed approach.
