Bistatic Ambiguity Function

To calculate the Ambiguity function for a bistatic Radar

function varargout=bisambfun(u,r,fs,cut)
%% Bistatic ambiguity function(u,r,fs,cut)
%
% This function aims to calculate the values of the bistatic ambiguity
% function of the signals u (the signal measured) and r (the reference
% signal), sampled to the fs frequency. The main advantage to use this
% function is just the need of the signals and the sampling frequency.
% The cut parameter is used to differentite the kind of results to display:
% '2D', it returns the Ambiguity Function in the Doppler-Delay Space
% 'Delay' displays the Zero Delay cut
% 'Doppler' displays the Doppler Delay Cut
