Abstract: | A new method is proposed in this paper for simultaneous frequency and directionestimation of coherent signals. The method is based on the rotational invariance techniques and uses an array triplet in motion to estimate the central frequencies and azimuths of coherent signals from narrowband sources. Without searching in the space of frequency-direction, the computational efficiency of the method is improved significantly. Simulation results in the typical examples demonstrate the performance of this new method. |
