Hi,

` If I have zk a noise signal (5000*1),which is complex gaussian noise .How can I find the covariance matrix ,so that I need the next step- to success such that inner matrix multiplication to be correct- also I have zm radar_received signal (5000*1),Also the multiplication is (p')*(inverse of covariance matrix)*(zm).I need the result to be 1*1,where p is target steering vector =exp(2j*pi*f*n),n is # of samples.I need to do whitening matched filter detection!!!!!!!!!!!`
