A novel Laser screen velocity measuring method with large effective screen area is introduced for some special velocity measuring occasions like wide spreadingrange or big-size flying objects.
But if above positive real condition is satisfied only within some frequency range, the convergence of FXLMS algorithm is dependent on the spreading of power spectral density of the reference signal.
