  • Alias suppression in pulsed doppler systems
    Patent number: 5048528
    Abstract: A Doppler velocity spectrum produced by radial projection in a two-dimensional Fourier frequency domain is processed to suppress alias spectral terms. The projected spectrum is divided into windows using an iterative algorithm which centers the spectral mean. The window containing data samples which maximizes a weighted score based upon the width and maximal value of samples within the window is used to determine which window contains true spectral components. Spectral components in other windows are then suppressed.
