Abstract :
A flexible and efficient approach for computing the bispectrum of finite duration determistic signals on polar rasters is proposed. The contour consists of equally spaced points over an arbitrary portion on the given slice. Using the Chirp Z-transform to interpolate the discrete-time Fourier transform, linear interpolation of the bispectral points, as required in a previous algorithm is avoided. The formulation is very general and applicable to computation of other high order spectra
