The zip file contains functions to calculate an Ambiguity Function (XAMB), Upsampled and Interpolated Correlation (XCORRU), and Coherence Function (XCOH). A prefilter can be specified in each function to "sharpen" correlation peaks.
XAMB calculates an estimate of the (cross-)ambiguity function. A record containing properties of the peak of the ambiguity function can be returned.
XCORRU calculates an estimate of an upsampled and interpolated (cross-)correlation function. A record containing properties of the peak of the correlation function can be returned.
XCOH calculates an estimate of the (cross-)coherence function. A record containing properties of the peak of the coherence function can be returned. |
