hello, i am trying find a null which is siting aside of a grating lobe.
theta_0=20 degrees so i cen find the angle of the grating lobe as shown bellow.
but i have a problem regaring the use of the second formulla(for finding the null ofthe grating lobe.
in formula 6-11 what should i put in beta so it will give me the null of a grating lobe?
