摘要:
The invention includes a real time spectral analysis of unsteady signals with complex values representatives of a physical phenomenon. Successive sections of a sample signal are modelled by a high order self-regressive process by estimating parameters characterizing the model by rapid Kalman filtering using an algorithm.
