Hello,
I am still trying to analyze an mechanic oscillation with my IWR1642 and DCA1000.
I capture all Raw data and get the 4 Arrays of every RX Channel, now i wanted to extract the Phase of each Signal in Matlab. I used the function "angle(x)" to get the angle of the complex number. After that i plotted this Signal but it doesnt look like the sinosoid of the mechanical Signal. I also tried to unwrap that Signal with the matlab command "unwrap" but doesnt help at all.
My Question is how do i Need to compute the complex number to plot the Phase corretly over time?
do i Need to subrtact the frequency term fb from the angle? with the 4Pi(BR/cT) in the pic below?
Thx for your help an greetings
Frederick
