Abstract :
A steering angle error compensation (SAEC) algorithm that is appropriate for a rapidly moving source environment is presented. The proposed method utilises a modal covariance matrix from multiple frequency components instead of the multiple snapshots in a narrowband SAEC, and estimates the steering error that maximises the output power of the modal space processing. As such, the steering error can be compensated with short observation times. The performance of the proposed method is demonstrated based on a Monte Carlo simulation.
